James Governor has noticed the same thing that many of us have - Blogger is the cesspool of the blogosphere, providing a huge number of the splogs that are out there. Yes, servives like Feedster could do a better job of filtering; but they wouldn't have to if Google just did some basic gatekeeping:

So far my evidence is just a quick snapshot, rather than something I have measured. But suffice to say of the spam blogs crudding up technorati for me, Blogger was the source of more than 50% of the total. Some myspace, one Wordpress.  

Maybe its just me, but to my mind causing pain at registration, and growing the splogosphere faster than anybody else, just ain't right. So Adwords is open to clickfraud, and now Blogger is emerging as the spam bloggers friend... Come on Google you can surely do better. Why not put some of those geniuses to work solving existing customer problems rather than inventing the future behind the GoogleWall?
