"I haven't been on SL in 6 months, and I went on the other night to attend a Burning Man event. They had about 60 people at peak, and it was so laggy it was really unbearable and local chat wasn't even functioning. Are those the kind of crowds we really want?"
That doesn't speak for SL, does it?
I mean, I myself love small events where you can actually use the local chat as a chat without loads of people spamming it with gestures.
But big events with 50, 60 or more avatars happen on special occasions. And if they really suffer from server lag, that's because the region server underneath the sim is unfit for the task. Hypergrid International Expo has recently changed from an OSCC-style around-the-sim-corners build with one sim for the stage and three for the audience to a single sim because you can throw such a lot at region servers nowadays.
Just recently, I was at a Woodstock-inspired peace festival. At least half the German OpenSim scene was there plus some more avatars from elsewhere. We were over 55 avatars at times. No problems. Some avatars took long to rez, but you have that all the time with today's unoptimised hi-poly avatars.
A bit less than two years ago, Juno modelled at a fashion show. There were over 60 avatars. Nobody had expected that many avatars, and I think they didn't even have seats for all of them. No problems again, only the viewer FPS tanked when she turned towards where the other models were stashed away. Granted, the sim as it was during the fashion show had no scripts running except for the chairs for the audience, and it was purpose-built for this event instead of being a big, multi-purpose var.
"Like our grid has a large portion of the SL Burning Man community, and they love having huge areas to build on."
Not to mention that you can probably pay less for a 4x4 var in OpenSim than for a parcel with a few hundred prims in SL.
"I still have no idea WTF people see in it anymore."
As you've said, many don't even know that OpenSim exists. Others have heard of OpenSim a while ago, but not recently, and they assume it's dead, just like many people assume SL has been dead since 2008/2009 due to lack of media coverage. Little do they know that OpenSim is about 80% as active as Second Life and has over four times the land area.
And of course, then there are those who have invested too much time and money into SL to leave so easily. But there's no reason to not take a look at OpenSim next to SL.
