I'd say... a small portion of the game population uses it. A lot of people do not know the lodestone exists.
You missed quite a lot. You missed the "love" triangle between a 30+ year old, 1 other guy and the current troll there, fighting over a 13 year old. It has died down a whole lot, but it was pretty bad early in the year. There was one women about 50 something that blasted one dude out in the open for trying to "get with her"...when it was really her fault for flaunting her sex life publicly which drew a lot of guys in, but one went a bit too far. Yeah that shit happened on the lodestone. The GMs take the lodestone a little more seriously now, but back then, the lodestone was completely unmoderated. The stuff people say on there is just.. really?
