I received a set of cards from meetmeme.com. In addition to my cards, they also provide the following URL: http://mtme.me/c89ab
I thought this was a pretty cool idea but with two problems:
a) My tweet count was wayyyy off when I got the cards. There is no way I only had like 4 or 11 tweets…
b) I just found them really hard to fit in my wallet. They are the size of baseball playing cards - which is by design - but they’re hard to carry around.
