I love that there are oh, 700+ people on these mailing lists, but we have zero visibility due to google not indexing them, where hackernews does. This is going to be an issue dominating the web (again, sadly) for a few weeks at least, and it would really help to be doing it there, rather than here:
https://news.ycombinator.com/item?id=37694306#37694307 As for me, up until tuesday I was trying to finish some technical stuff, and I have a proposal due sept 30 that I have not started yet. I regret now, even mentioning it on these lists. Please go forth and find a forum with new folk to debate with? I do look forward to whatever is supposed to be announced today(?), and reading it thoroughly, and I hope that instead of starting with decade old positions, that you assemble your thoughts, as to whatever the FCC is actually proposing moving forward. Ideally, in order to participate in the legal process, we would need to file a NPRM, which I am willing to co-ordinate.
