Yep….here’s another Twitter extension that makes it really simple to add photos to your Twitter stream called TwitPic.

Go there, login in with your Twitter credentials, and upload a photo or send one from your phone. You can see one I just took with my iPhone (I’m at the Eden Prairie library) and emailed it to my ‘special’ email address with the subject line, "Eden Prairie library, bits vs. atoms." I used this subject since I’d just sent a tweet that, yet again, I was struck by the huge numbers of people here on the computers (viewing bits) while few of us are here for the atoms (books).

Though moblogging has been around for awhile and adding a photo to blogs and other services has been relatively easy for some time, there’s something about the off-handed tossing up a photo as a tweet that makes the immediacy of it compelling.

For more of how Twitter is turning into a platform and to see other extensions, look here, here or even get in touch with your inner Twitter.
