This may just be me, but in my experience the companies that spend $1500 on a PR wire release every couple weeks is putting more effort into propping the stock price, and therefore their borrowing power, than actually managing the company. Constant PRs are big red flag to me. PRs aren't necessarily bad, but when you have no revenues the previous quarter I'm ok if you try to limit your expenses somewhat.
The PRs are not free and if you're not relying on your equity to continue funding operations, they aren't really a necessity. They can let the quarterly filings drive the stock. Brian was on Benzinga not long ago in a video interview though, so they haven't been silent. I don't think he paid for that, but you never know. And there's been some twitter posts.
