eh, active users decreased sharply a few years back, but they're staying pretty steady
a few months ago i saw 7,000 online, today it is 20,000 - for users online at one time that's a pretty solid population
Considering 50,000 used to be an average with 90,000+ for a daily peak, I would very much disagree. The market speaks for itself as well. 80k active listings? That's pitiful. It used to be twice that 4+ years ago.
I don't follow this site much anymore, but numbers really do speak for themself. Gaia's biggest problem was injecting the market with so much cash crap. It oversaturated the market and never let up from there. Rarity and value of older items has barely budged in the last 5+ years.
