We have been hearing a lot lately about how Flash is a dying technology and how it’ll soon be replaced by HTML5. Personally, I think that it will slowly replace Flash for some things, but Flash will always have a place, especially for developing complex games and rich internet applications. If you’ve yet to see what HTML5 can do, I’ve rounded up 10 demos that show off some of its capabilities.

So what do you think – will HTML5 replace Flash?

At DEMO this week, my6sense will be launching its free Attention API, which allows third parties to tap into the “digital intuition” technology that my6sense utilizes.

My6sense is a mobile app that basically gets to know what you like and what’s important to you, after which it organizes and filters your different web content — RSS feeds, Twittermessages, Facebook updates — based on your preferences.

The app gets more and more accurate the more that you use it, because it can take advantage of monitoring how long you spend on certain articles, what type of authors or content you gravitate toward on a certain source, and what type of information you find most useful.

My6sense already has an iPhone app as well as a Twitter tool called myTweetsense; the Attention API is the latest addition to the my6sense stable of tools, allowing publishers integrate their own feeds into my6sense, so that users can get personalized content from that source. This data can also be integrated into other mobile applications and also with other services.

A possible use case would work like this: A user could choose to subscribe to a my6sense stream ofMashable.com and in turn would get served the content that they most want to see in order of importance and interest. So instead of having to go through all the articles in an RSS feed, the most important stuff will bubble up to the top.

My6sense is useful and usable as a mobile application, but having that type of technology expanded to other apps and other platforms makes a lot of sense. The Attention API will be in closed beta for a few months, but potential Attention API partners can sign up at my6sense.com
