RSS Bandit provides users with the ability to perform searches from its toolbar and view the results in the same UI used for reading blogs if the results can be viewed as an RSS feed. This integration is provided for Feedster searches and I was considering adding other blog search engines to the default. Torsten had given me a RSS link to some search results on PubSub and they seemed to be better than Feedster in some cases. So this evening I decided to try out PubSub's weblog search and see if there was a way to provide similar integration with RSS Bandit. Unfortunately, it turns out that one has to provide them with an email address before you can perform searches.
I guess they aren't in a rush to have any users.
