We have just launched the public beta of RankSpeed.com, a new search tool that ranks websites, web services and web apps by any sentiment from the blogosphere / twittersphere.
What are the most useful twitter tools ? What is the most effective antivirus ? What are the best webmail ? RankSpeed will instantly answer these kind of subjective searches by aggregating opinions from the blogosphere and the twittersphere.
We hope that you will find this service useful for finding and comparing web results ;-)
