Not very useful Rated 2 out of 5 stars
The idea is great, but 1. it doesn't support Unicode (I guess?), which means that googling via Cleeki for - say - "małżeństwa", redirects me to a Google search for "ma³¿eñstwa". Not being able to properly handle foreign language characters looks pretty lame, given that it's 2012 already. 2. Adding new, custom channels (other than predefined ones; Bing, for example) is unintuitive and requires some "reverse engineering", as the configuration dialog doesn't bother to describe the meaning of the placeholders (such as [kw] or [cs]) one is expected to include in urls.
