In the vast majority of today’s websites, if a program is required to pick out a particular part of a HTML page, such as the main article, the sidebar or the top navigation, it would have to be programmed to do so on a per website and web page basis. This is because every website structures its HTML differently, unless based on an underlying package with a consistent HTML foot print.

Most current websites therefore use a variety of <p>, <div> and <span> tags to surround their content. These tags define style and do not obviously determine whether the contained content is part of the website’s navigation system or whether it is the main article or focus of the web page. The new HTML 5 tags aim to change this by explicitly defining content.

Defining content with specific HTML 5 tags will make websites easier to parse by computer programs. This could benefit accessibility readers for the blind and allow content aggregating systems and ‘mash-up’ websites to easily parse, link to and cite your articles. Content aggregation and automation of web page content retrieval is quite fundamental to some of the newer Web 2.0 sites and social networks. Good examples being Facebook’s automatic retrieval of web page information when a link is entered into a status update, or Reddit’s automatic thumbnail generation based on images found within the linked web page.

Here is a listed on related HTML content tags, as available from the W3C Schools website.

• <article> – Defines a main article on a page. Can include cite (citation) and pubdate (publishing date) attributes.
• <details> – States content details for a specific section. Can include an open attribute defining whether or not the details within are visible to the end-user.
• <figcaption> – States the caption for a figure as defined by the figure tag.
• <figure> – Usually used to group a set of elements.
• <footer> – Footer layout element. This is used to contain the footer content of the page, usually contains the website name, author and copyright information.
• <header> – Header layout element. This tag is designed to contain the top header of a document, usually showing the website logo, page and/or company title and subtitle.
• <hgroup> – A tag used to group together heading tags such as <h1>, <h2>, <h3> and so on.
• <keygen> – A key generation tag which defines a generated (encryption) key that can be associated with a HTML form.
• <meter> – The <meter> tag contains content which is deemed to be a measurement of some sort.
• <nav> – The <nav> tags stands for navigation and is designed to surround navigation links, such as those present in a sidebar bar or navigational header/footer.
• <summary> – The <summary> tag defines the title of a <details> element.
• <time> – This tags contains content which is a statement or measurement of time and/or date/time.

Unfortunately, it is likely that HTML 5 content tags with not be adopted completely for quite some time and there will likely continued use of existing HTML mark up and related styling of <div> and <span> tags for quite some time.

With the currently in development, Ubuntu 10.04, codenamed Lucid Lynx, the development road map is set to take huge advantage of the major social networks. Common social networking actions, such as updating your Facebook status, or sending a Tweet to your friends are set to be integrated directly into the operating system allowing users to keep their friends up-to-date and share information without the need to even open a web browser.

Take a look at the image below. This is a basic mock-up of the new social menu codenamed the ‘Me Menu’, which is aimed to become to a simple, centralised way to manage your social activities. It has options for a user avatar, multiple social networks, instant messaging and microblogging services and the setting and broadcast of custom and preset statuses and microblogs.

This clever menu will link into other social applications, like your instance messaging application. In others words, you set your status in the me menu, and the update is reflected automatically in all your social networks and configured social applications. Related to this, in the diagram above, ‘Chat Accounts…’ will refer to all forms of instant messaging and direct communications, while ‘Broadcast Accounts’ will refer to social networks which allow you to share a status update such as Twitter, Facebook and identi.ca.

The Ubuntu One service will also be integrated into the Me Menu and Ubuntu’s new social infrastructure. This will allow social network information to be synchronised and related to your Ubuntu One login, along with the existing file synchronisation, contact management and note synchronisation services already offered by Ubuntu One.

The Me Menu will be the overall representation of ‘you’ within Ubuntu. If you want more information regarding the Me Menu, which is to become the central social network integrations of Ubuntu, you can take a look at the design specification.

Facebook founder Mark Zuckerberg, wrote the following in an open letter to Facebook.

“However, as Facebook has grown, some of these regional networks now have millions of members and weve concluded that this is no longer the best way for you to control your privacy. Almost 50 percent of all Facebook users are members of regional networks, so this is an important issue for us. If we can build a better system, then more than 100 million people will have even more control of their information.

The plan weve come up with is to remove regional networks completely and create a simpler model for privacy control where you can set content to be available to only your friends, friends of your friends, or everyone.

Were adding something that many of you have asked for – the ability to control who sees each individual piece of content you create or upload. In addition, well also be fulfilling a request made by many of you to make the privacy settings page simpler by combining some settings. If you want to read more about this, we began discussing this plan back in July.

Since this update will remove regional networks and create some new settings, in the next couple of weeks well ask you to review and update your privacy settings. Youll see a message that will explain the changes and take you to a page where you can update your settings. When youre finished, well show you a confirmation page so you can make sure you chose the right settings for you. As always, once youre done youll still be able to change your settings whenever you want.”

What do you think? Should Facebook change to this system? Are the regional networking features redundant now or are regional networks useful to you?
