Which LMS do you use and why?

I have to agree, there is no perfect LMS. We dropped Taleo because it was not at all user friendly and "buggy" with its reporting feature. It was also more robust than we needed . I'm sure it works well when "robust" is desired. We went with Litmos which was very close to what we were looking for in an LMS. Most of all it's user friendly. We hired new people who picked it up in a matter of hours with very little help from Litmos. It has its shortmcomings but we can live with them.
