Blekko should be renamed Sukko.
Searched for Webmaster Forum and the top results are pinterest, an iTunes app for V7N, a UK webmaster forum I've never heard of, a Google Support Forum, then a twitter directory. The bottom six are populated by WebmasterWorld, searchengineland, a single member profile from SEOMoz, bottoming out with highrankingsforum and searchenginewatch. Not useful.
I did a search on "How to catch stripers" and the top result was a news report about a fishing derby, followed by a cafepress mug, etc. Not useful at all.
Did the striper search on bing and while it's returning garbage sites like eHow, at least those pages answer my question. Google does significantly better, despite also returning non-authoritative pages from eHow.
The above is constructive criticism. Blekko has bigger problems than their interface.
