Mi laboras ĉe internacia kompanio, sed (triste) ni ne uzas Esperanton por komuniki. La angla lingvo venkis. Mi ankoraŭ ŝatas paroli Esperanton por amuziĝi.
(I work for an international company, but (sadly) we don't use Esperanto to communicate. English won. I still like to speak Esperanto for fun.)
Likewise, I work for a small but international company, and am the only Esperantist here. With only ~100 employees, though, we speak ~20 languages (myself: en-us natively and eo with frequent mistakes and vortara uzado, plus a working knowledge of advanced classical la and basic es-mx).
Mi havis trovita ke Twitter estas bona ejo legi kaj lerni Esperanton kaj interrilati kun aliaj Esperantisoj.
It's around 350 people at the moment, on every continent but Antarctica. I suspect that the talent pool of English speakers is larger than that of Esperanto speakers and that they didn't want to add an additional burden to the hiring process by asking people to learn another language. In fact, we have an internal list of who speaks what languages and there are only two of us listing Esperanto, and neither of us is fluent. (Though I could probably be there in 1-2 weeks of serious effort.)
Mi ne aktivas en multaj Esperantistaj forumoj... mi ne kredas ke mian Esperanton estas sufiĉa bona. :) Sed oni kapablas kontakti min ĉe launchpad.net. Mi estas 'fader' tie ankaŭ.
OT: I'm surprised how well I can read Esperanto, although I - of course - don't understand everything. (I speak some German, English, French, Spanish, Italian and Portuguese.)
It's made to be easy, and part of the effort to do that is making the vocabulary as trivial as internationally feasible. There are languages made to be even more directly understandable, like Interlingua, but they are a bit harder to pick up as an actively used language as you have to learn a lot more words to be able to talk about things. Esperanto provides shortcuts to say a lot with just a basic vocabulary.
