So I bring you Plodt.
Plodt on Twitter, you enclose keywords in asterix along with a number. (it also tracks hashtags). So for example:
"I just won the lottery!!! *happy10*"
Now for the experiment: Ya ready? For the rest of the month, when you're *thankful* for something (tying this in with the holidays, get it?), tag your Tweets! It will be fun to see what everybody is thankful for at the end of the month/season!
