About time ;)
One of my side projects over time has been to try to keep contact with the SE diaspora, folks who were in SE previously, in the hope of bringing the community home at the right time. Some of those communities have been away for over a decade - and many of the folks don't really believe things can be saved.
I'm a bit of an optimist, and to paraphrase the lord of the rings... perhaps, just perhaps There may be a light beyond the darkness; and if so, I would have us see it and be glad. I'm not sure what that would look like, or see clear signs of hope, but its essential to rebuild the hearts of many communities.
I think something missing - and worth considering, not just about your periods of tenure, but also the past, is to look at where the company has fallen short of building trust, where words were said but not followed up on, or wrong words were said, and how perhaps those breakages in trust be addressed, not from a place of blame, spite or recrimination, be because its the right thing to do. To understand where folks might do better, and find better ways to communicate both ways.
Rebuilding trust and goodwill's essential, cause then people talk to you, and trust you - and that's somewhere the company's done poorly for years.
That's a heavy thing to ask.
Many initiatives are focused on the new but forget the fundamentals, or the communuitycommunity we have - and addressing the needs of the folks who are, were or have been here would help a lot in trying to rebuild trust and re-engaging folks.
We've a decade of baggage, and it would be good to make a start of unloading it.
A lighter thing would be to try to find a community, or chat where you'd want to see activity, and see if you can hang out, and spark a conversation. Not 'just' as duty, but as part of getting to know the community better. (Admittedly, I'd pondered the idea of going to 2-3 community chats a week, throwing the floor open and seeing what happened but that might be a bit too much for most ;) )
In general better communication would help I'd say, and more natural communication.
Another long running challenge has been that smaller communities, heck anything smaller than SO tend to get ignored, and they do feel it. Trying to rebuild confidence with those communities would be nice - as a long term 'incremental' project rather than a big one. We kinda need a voice - and we don't really feel we have one a lot of the time.
