It's the lack of really small, niche, but still relatively active communities that is the biggest loss for me (so far). For example, I want to to talk about Brentford FC, a tiny English football club which was only promoted to the Premier League a couple of years ago. But we're a million miles away from that when there are exactly two communities for general soccer and one community for Liverpool FC, all three with exactly one subscriber.
Any other Bees fans out there? This Flekken guy seems pretty promising, even if I had hopes for Alban Lafont.
