Wow, HTML 5 had a brilliant time at Google IO last week. Here’s a recap of some of the top news coming from the event regarding the technology.

Among the plethora of announcements and releases made at Google IO, a new major feature for Chrome was announced.

The Chrome Web App Store aims to bring the app store experience you get on the iPhone and Android to your web browser. It allows application developers to turn their sites into mini app listings, which users can then link to in an enhanced bookmark-like way from their Chrome home screen.

Remember that awesome demo done on-stage at Google IO’s day 2 keynote? (If not, I embedded it below).

They showed off Froyo’s data push system by having a Chrome extension, that when clicked, opened the same web page you were viewing on your Android phone.

Now, you can go download the application to your phone, and install the Chrome extension, and everything just works!

A few days ago, I was at a Google-organised event in London talking about open source technologies and how they form the foundation of various projects.

I was first last week to break news of Quake 2 running inside Google Chrome, which was demoed at the event – awesome!

Chrome, Google’s web browser, has a cool feature in it which allows you to add custom search engines. For example, you can create them for Google, Yahoo, your own blog or whatever.

But they are pretty generic in nature. This means you can quite easily add some extra cool features to Chrome without very much effort at all.

Here, I make a couple of cool Twitter extensions, that allow you to construct a tweet and find a user quickly.
