I edited heavily for a few months, contributing some knowledge to articles on library science topics, also contributing some new articles, and then after a while becoming mainly WikiGnome-like, mainly reverting vandalism and making other small changes based on my 500+ page watch list as part of my time wasting activities. Then I sort of lost interest in editing Wikipedia. I rarely do any edits now and I don't log in frequently.
I used to be a librarian, and now I run Library Juice Academy, which offers online professional education for librarians. We also publish books for the same audience.
