I was also there in Eclipse's embryonic phase and might actually have known your brother, as I was a co-op student at OTI at the time. Since then, and after a largely failed attempt in 2008 to use it to leverage IBM UIMA properly (too clunky, over-engineered for throwaway research development), I have never really bothered with it. Oh, that's not true, a stint at IBM Research in 2008 meant I was forced to use it. Emacs and print statements for me, especially since I might use multiple minority languages in a given project and, at least until recently, most of them weren't well supported in the Eclipse IDE.

Sorry IBM/OTI, can we still be friends? Even though you migrated Lotus Notes and that IM tool to an Eclipse base?
