i could go on and on about social applications and their usefulness (or lack thereof?), but i think i won't. i just don't have the time right now. however, i've found that there are now tools that do the thinking for you. like what, you ask? well for assessing twitter's value there are a whole slew. one such tool is called tweet o'clock.
what's it do? well, you type in the username of anyone without protected tweets, and it spits out the day and time that user is most likely to be on twitter. why would you care? if you're looking to use twitter as a communication tool, then knowing this information would help you know when others would be most likely to see and respond to your tweets. i guess. it's all just so fascinating.
