new to me Web 2.0

I tried a couple of things that are worth sharing.
I signed up for an account at Thinkature.com and while it loaded incredibly slowly and my workspace was lost as I was uploading an image, this is an idea and collaborative tool worth going back to and trying again. In theory at least (as I mentioned, I didn't actually get it to work), it's a virtual whiteboard; the creator of the workspace invites others to text or voice chat, type/edit text, draw, link cards/ideas in real-time.
Another social software service/site I signed up for was 30boxes.com. It's an online calendar/social aggregator hybrid. Again, this is sort of one-stop, catch all the updates at once which is definitely useful, but I am starting to wonder where all of these conveniences start to become more of a burden than the collection of people, dates, and posts we try to keep up with. I realize we are an unusual group in the sense that we have accounts all over the place with duplication of services, but isn't there a risk that the means become (or at least overshadow) the ends?
