I've been playing with my interests list, copying stuff from friends, that sort of thing.
Along the way I decided to add some professional interests relevant to being a Business Analyst in.
Evidently I'm the only person on LJ interested in "unified modelling language" or "business process modelling". (UML gets considerable hits)
A significant chunk of the few people interested in "use cases" are Russian (judging by the cyrillic text). Ditto for "business analysis" (one of the two communities that produces is Russian).
I would have expected professional interests, particularly from the fringes of IT, to feature fairly heavily in the english-speaking audience.
I'm kind of wondering why they don't.
