where have i been?

...or better stated, where has February gone! been a busy month...still recovering from the superbowl...and a birthday trip for yours truly.

so what's top of mind this week...more web2.0 (or can we say we're on to 2.5 at this point) features that are interesting...even if not quite complete businesses.

one is Sphere...they've gotten some traction with publishers (TechCrunch, Time to name a couple...scroll to bottom of a post or article on these sites and click on the Sphere link), and their implementation is clean and intuitive. they even have a smattering of a business model in that their pop up with links to related content carries an IAB standard ad unit. they're in the mix with the other web2.0 guys trying to engender user engagement from story pages...but they have a nice app. curious to see where users gravitate in this space with the mix of Sphere, Digg, Delicious, Netvines, et al.?

the other is pbwiki...again, not exactly clear where we draw the line between a blog, wiki, message board, etc. these days...but the pbwiki site is pretty easy to use and to set up a wiki for any use -- business or personal. from a business model standpoint, they seem to be heading down the free w/ subscription upgrade path that we are all familiar with in the online world.

worth checking both of these guys out.
