I generally spin across TWW, TGN and Wargames, News and Terrain every day, along with a few choice forums such as Lead Adventure. I have not been on TMP for months. I find it very claustrophobic.
As for FB, I run several closed groups, including ones for our own games and a few related ones. I am also a member of quite a few manufacturers and designers FB pages. It is what it is and there is no point in grieving over it as small fry like us will never change it.
I am a member of the Beasts of War backstage and a regular listener to the Meeples & Miniatures and The Veteran Wargamer’s podcasts.
Of all of these I find Meeples and TWW the most informative.
