Current events, politics, and whatever i'm reading at the time (mostly science and politics and economics).

It hasn't really done that in my experience. There will always be people who just don't use the IRC server, you can't embed pictures or soundcloud files, and in general there is always content that drives people in the chat room back to the forum.

To be honest I thought you already had to comment on two other people's posts with critiques before being able to post any of your work. I'd definitely second the idea of setting a post limit (maybe Subsonics can't post new songs? Maybe even Sub Basses?), and some sort of ranking system so people can be aware of what the producer's skill level and how they should approach their feedback. It's a little frustrating to look for feedback and get "oh wow this sounds amazing great job!!!!!!" as a response, so helping people find peer groups, mentors, and pupils might be beneficial.

Currently working on subfolders for the different sounds (i.e. tonal kicks/top kicks/punchy kicks), and organizing my foley and SFX folders.

Not pictured: acapellas folder (needs organizing), personal foley files and other field recordings, stems from remix comps and other places, and my slowly developing personal "sample pack".

As far as how to organize your samples, here's how I went: I made a whole bunch of folders and subfolders (similar to picture), and I opened two finder/explorer windows - one with all my purchased samples, one with my new organized folder system. I listened through and started dividing everything into its proper place. Took me like 3-4 hours, and it's really tedious, but it helps a lot. From there, you can start further subdividing the samples so you can just find them ASAP, deleting samples that seem to just clog up your library (i'd personally move them to a "Trash Bin" on an external hard drive just for archiving but it's all up to you), and eventually finding the sounds you really like and putting a duplicate into your own favorite samples folder.

Ideally by not sharing EVERY idea you ever make

This is something that took me almost a bit too long to realize, and has already cost me a few contacts in the music industry (I can only hope I didn't burn any bridges while doing it) before even getting started. It's great to be excited about your own growth, but allow people to come to you more organically - trust me, once you start to stand out from the crowd they'll take notice.

Pretty much all my social media (skype/twitter/snapchat/etc) is mussarmusic

feel free to add me!

It's kinda neat to mess around with, but if you have an understanding of music theory it really doesn't do anything besides give you ideas for various rhythms (which you could also do on your own by making those chords and experimenting). If you don't ever plan on really going deep into theory and live in the piano roll, I can see it as a good buy but I don't see myself using it in the future except as an educational tool for teaching theory or helping with ear training.

Really digging this! To expand on the female vocals idea, you could totally throw a female vocal sample into a sampler with some looping and portamento and play a nice lead melody over this to give it some emotion and something for the listener to sing along to.
