What is bla.st on my lower sidebar?

It's a widget that display "cards" on blogs/sites for free or just a few cents a day(optional).

Currently, I made one for the current contest and got new visitors because of it(welcome). Once the contest is over, I will still be able to display it for free but my card will be in a lower position versus the paid one. Also, the sooner you get one, the better your overall position in the free cards.

For example, I made one 3x3 with the "blog" category.

It's a cheap way to bring traffic to your sites because of the a fix price per day. Just click one of the link above.

P.S.
It was recommended a few week ago by Tim(thanks).

I'm waiting to see how it goes after the contest. I will have to redo my card.
