Michael over at Tame the Web has recently become enamored of Jybe, and seems to have experienced the same good customer service I did back in February. Seems that Jybe has been listening to folks, including librarians, and is addressing several of the shortcomings that we found in our initial tests with this product. Will definately replicate the tests when 2.0 comes out and will provide an update then.
Michael's a little worried about whether users will install a plugin, and I have to agree that's still a shortcoming. I wonder if something like this can be incorporated into the toolbar I'm still plugging away at? If there's an overwhelming added value to something, surely the users will have less reason not to download?
