Sounds like you are going to like it here. People here don't really like or use memes (at least in such intensity, there are still some :P) and while conversation can indeed turn into a bit of a shouting match, even then you will see people citing sources and making points. If you would find some old topic as interesting, you can still respond and likely revive it. Hubski does not have the thread archival in place where after six months it freezes.
If you would have questions, please don't be shy and ask. If I will not know the answer, someone will. From the top of my head, I can recommend you #pubski (new thread every Wednesday will be created under this tag, it's a pub-like setting where people just tell about new stuff in their life) and bfv's #weeklymusicthread. Here are the Latest Pubski and Latest Share Your Music threads.
Also, if you haven't done so already, please read the Hubski Primer and maybe the FAQ as these are here for a good reason. ;)
