Meg and I are starting to build up "search user personas" for the next phase of the design of Trexy. We're actively looking for people to tell us how they use search engines and what motivates them. Why? So we can tune in the 'interaction design' for the next version of Trexy. We want Trexy to 'scratch an itch' and hit the mark for blog publishers, topic-specific search engines and search users.
We've picked up a lot from attending conferences, the Flag & Bell, and witnessing the sins of search so we already have many pieces of the puzzle but this is a tricky design problem - fortunately we're still having fun solving it!
