I really wish there was a thorough analysis somewhere of what kind of semantics results in something becoming a 助動詞 instead of a 接続助詞 (or something else).
Things with strong modality or effects on tense or aspect seem to become 助動詞, but that's a rather vague understanding of it.
The really interesting part is that things do specifically shift from 助動詞 to 助詞 when they lose some of those attributes (both て and たって went through this process, as well as べ from べし), so it's just that things need to directly modify the verb when they are changing its tense or aspect, but they need to not modify the verb when they stop doing those things.

I'm not sure how it goes on the bigger sites, but if my memory serves me correctly, the only real difference on JLSE was that it was more active, which was nice.
In particular it seems to encourage more activity from regular members, and most of the noise here comes from non-regulars, so for the most part I think it may have even increased the SNR.
Personally I find it pretty fun, which is nice, since it livens things up a little bit for me at least. :-)
