bla.st is some kind of pretty. Lot of images linking to websites, free or cheap listing or advertising. I put up a card for CMoore Fine Art Studio today and I think it costs a penny a day. Plus, they give you 2 extra cents a day if you blog about them, which is great for me, a starving artist and all.
I also gave them a link, while blogging about them, which I recommend, seeing as they give you one on their gorgeous and popular website. You can get into the top position by paying the most, which is healthy. Free and new get listed last, which is fair to everybody else.
I think the domain name is for somewhere in space.
