I think a part of the problem there may be that a substantial percentage of the original user community are perl hackers, and tend to discuss their Gearman usage in the context of whatever else they're using - I see Gearman discussions reasonably often on the Catalyst IRC channel, for example. Another reason is quite possibly that for the vast majority of tasks, Gearman "just works" - if the obvious way to use a piece of software works first time, talking to other users isn't particularly necessary (there's not really a GNU cat community either, for example :) I'm not entirely sure what you'd do to fix that though (or even if there's anything except perception to be fixed)
