At least till we know who bought blo.gs, I’m not sure I want to pinging them:
Blo.gs has been sold to an unnamed individual and will transfer ownership, including account information and user data, sometime on or around June 13. Blo.gs is a directory of recently updated weblogs. It is “pinged” by virtually every public blog as they are updated. I wonder if this individual who purchased the site will subsequently flip Blo.gs to a search engine trying to build a blog search tool.
