Take a look at this ego feed from PubSub: It is taken over by spam blogs, every one from Blogspot.
Is it time for tough love: Should PubSub, IceRocket, Technorati, et al refuse to index Blogspot blogs until Google does something? Google, after all, should be the very best placed company in the world to deal with spam sites. Funny how the similar ego search on Google blogsearch turns up no spam. Google needs to both fix Blogspot and share its secrets for ignoring blogspam.
