Okay, I've read through the 50 profiles and a few look cool. That said, anything around developer's tools, gambling or video games aren't interesting to me.
Also, I think the point of this post is not to highlight an angel investment opportunity, but to show a few directions the web is going in (that's the kind of grammar up with which I will not put!).

This enriches news stories. For bloggers, etc, you annotate a block of text and that annotation is shared in some way with others. So, say there's a CNN story on something like "McCain apologizes for pig ad," a million people could annotate that "meme" and come to some wisdom-of-the-crowds solution for what it means.
Applied to all web content, it could be interesting.
Revenue stream: not obvious.
Yammar. It's like twitter, but for colleagues. It looks like there is a single webpage with status updates for everyone. Ie. "finishing the headline; mocking up the icons; testing the mail lists; brainstorming"; etc.
Mass customization of interactive content, for the non-technical writer. (ie. if it's raining today in the home city of the web-site visitor, a cute joke about that is the headline.) I think this will feel weird and forced at first, much like those animated paintings must have seemed odd when Hogwarts first got them. But, seriously, how much more rich can you make media?
On the other hand, there's a small chance you'll visit this website on an iPhone and it will advise you to flush.
This gets a gold star. Widgets are sorta neat, but tingz are widgets built specifically for mobile computers, and which are meant to work across platforms. In my future, people will have screens with magnets stuck to their fridge. They yank them off, add a few items to the grocery list, and check out their schedule for the weekend. Ten minutes later, the husband goes into the grocery store and sees a his updated list on his iPhone. (Or robots just anticipate and fulfil our needs; it depends on the time frame).
I don't know what this is, but it caught my eye. I think you enter a track a wide range of personal metrics (weight, HR, $ life savings, weekly run mileage, avg. commuting time) and then do something with it.
You wear a thingy that tracks all your personal health activity and then it wifi's it up to a site that analyzes and reports the exact minute of your death (I made the last bit up.)
Swype.
This gets my second gold star. It could totally fail, like the guy who invented a keyboard that was better than QWERTY like a century after every secretary learned QWERTY. Or it could succeed like the BlackBerry's little buttons.
It's a better way to enter text on tiny keyboards. The company is really just an algorithm that forms words based, not on tapping keys, but on swiping a pen over a flat screen image of keys. So it's still QWERTY, but much more fluid. A small change, but if you can go from 10 WPM to 50 WPM on your iPhone/BlackBerry, it's good.
What caught my eye is that the co-founder invented T9; that predictive typing app. for SMS that's on like 2.5 billion or so phones.
Turns your desktop into a wormhole. Except instead of sending documents to a universe where Sarah Palin is POTUSA, it goes to another desktop. Like your home one when you're at work. Coolest part is that it appears to work without you having to do anything special. Just put a doc in a folder (a magic folder).
