Right on Mike! I used to do the same thing with 1-pixel frames back in the pre-Ajax days.

I got an email about a reply ... your comments count says (2) ... but I don't see your reply here ...

one project is an app called "tweet comply" for Advisor Products, Inc. out of NYC.

another project is an extension of something I did for a charity ad campaign on June 8th, where we pumped content out of Twitter onto Times Square's Specta Color HD, along with photos and video and other stuff.

the collaborative project I can't talk about too too much ... SaaS startup, I'm doing integration analysis for a suite of products they want to offer via one central portal.

the other project that it looks like I'm starting is a fairly straight forward CRUD app for a law firm that deals with utility collections. some encryption involved, some Workflow-friendly workflow that I think we're going to implement in WF. Very early in discovery/analysis, but also doing what we can in terms of immediate triage, as the client's former team blew her off, shut off her server, gutted the code last week.

I'm working on two business apps in the twitter space myself, obviously 100% social media right there. Working on two other projects as well, which simply have little/no social media tie-in. One does have collaborative aspects ... and we're in the very early design phase ... so maybe there would be some benefits to going social there.
