As someone posting my resume, I actually found it very valuable -- at least for me. I had five different companies reach out to me, and all of them were relevant. Three of them sound very interesting and I am optimistic about those.

I don't think I would have connected with these companies outside of a thread like this. I don't think they have their jobs posted on any of the sites I use (except for one of the opportunities).

As far as concerns, I can see how this thread would have a lot of noise, though it seems most of the postings were of decent quality. But I could see it growing in size, and the noise may overcome the signal at some point.

As far a recurrence goes, I think this should be based on the feedback. I can see how it would be valuable, and it certainly has already been for me, though I hope (thanks to this thread) that I won't be needing it next occurrence if it were to happen, or even for a long time to come.
