I've gotten about two years worth of contracting work from posting on one of these threads. A lot of tire kickers, and a lot of "take this test and then we'll talk" offers as well. I just ignore those, but I think, in general, it's not a bad network facilitator.

I had a company reach out but they were east coast and remote wasn’t an option for them, and relocating not an option for me. Ces la vie.

I have. I've also met several long term clients with interesting projects via the "Seeking freelancer?" thread as well.

I got an interview last year. It was a very good match, but bad timing for them and me and we didn't move forward with it.
