so does 2nd still have support by users like well made home brew and rule fixes

Some. 2e is a little lost in the OSR, too late to be considered entirely "old school", but to early to have OGL content like 3e. Most of the OSR (Old School Renaissance) retro-clone games are clones of Original D&D, Basic D&D, or AD&D (1e). The only 2e retro-clone I know of is For Gold and Glory, so there's that, and you could check it out. That said, 2e, particularly early 2e material, is just a clean-up of 1e and the systems are quite compatible. So any new material put out for, say OSRIC, is totally usable in a 2e campaign. Dragonsfoot.org also has a fairly active 2e board where people discuss home brew rules and such, and in general is a great site for folks interested in playing TSR-era D&D.

Dragonsfoot.org has been mentioned.

The thepiazza.org.uk is a separate forum that sees steady activity.

There's a metric ton of Facebook pages, some more active than others.

And there's drivethrurpg and the whole catalog of TSR/WotC 2ED library in all it's glory.

And, of course, folks around here talk about and post stuff a lot. I have some 2e-compatible stuff on my blog, and post the occasional bit in Homebrew. AND, because 1e and 2e are so compatible, you can use a lot of 1e stuff without much alteration.

Less than most other editions, but enough one can find all the advice they might want

While there are some important differences between AD&D and D&D like in the Rulescyclopedia they are also very compatible. I remember running an AD&D 2e game using an adventure for RC D&D and at the time not knowing that it was not for AD&D though I did notice some weird things such as all the elves seemed to have a class of elf but I just thought it was just short hand to not have to describe each combo of classes each time and the fact they were all fighter/mages was a coincidence (I was young so sue me).

All the TSR versions are fairly compatible, so long as you pick a ruleset and go with it (even if your ruleset winds up mixed and matched). It creates a great breadth of material to work with.

I wind up with a weird mishmash of rules from all of the TSR editions personally, plus a few elements of a couple of retroclones (Hackmaster is a big one), but it still kinda works since the system's so heavily modular.
