Brady on Sphere's Blog Search.
Tweet Posted by mofoghlu at May 24, 2006 8:44 AMSphere launched a month ago, but i only just got to really check it out last week when i sat down with tony conrad, ceo and founder (Tony was previously involved in Oddpost and is an advisor for Automattic). The technical team is the crew that brought us Waypath.com - an early blog search engine.
Sphere is an impressive blog search engine and one that is sure to rise in traffic. In a very short time it has already reached feedster's traffic levels and surpassed Pubsub (they have a while to go before reaching Technorati).
As they build their index they are focusing on avoiding splogs and pulling in quality (reminds me of techmeme.com's approach). Their index allows for a search to run over a 4 month period and they have a very useful UI element that allows you to see the post distribution for your query. You can use this tool to focus your search on a custom date range (the default for a search is a week).
