It may more be that you're just in the stark minority. The software's primary function is livestreaming... people who just want to use it for local recording are few and far between. Not to say that they're unwelcome, but most people will assume that you're trying to livestream (unless very bluntly and clearly labelled otherwise in the thread title and post body) in their responses, which tends to use radically different settings than local recording can.
So yeah, you might get some face-palm responses from people who miss the 'local recording only' disclaimer, if you say that you're using a 30mbps bitrate. Which is WAY too high for livestreaming to most of the popular sites out there, but works fine on local, without the bandwidth (or remote ingest) bottleneck(s).
You also may not get many responses to local-only questions, as local-recording isn't what most do (aside from mirrored archival copies of their livestreams). But that isn't hostility, it's just that many won't know, as it's something they don't really deal with.
