Second Life needs to seriously expand, putting it on steam would give it some attention. No, Steam is not just for gamers, there are creative platforms on steam too.
Alot of people complain about the graphics in SL or that it is filled with trolls and griefers.
Well, the only way SL is getting any attention right now is from Trolling and griefing videos on youtube which only makes more want to try it. Britbong, Estaban Winsmore, Oliver Sargent, Cleptar, The Bad Guys, Derrick, Lavender Storydel are some of the channels i found making videos like those with quite a lot of viewers.
As for graphics, SL needs to update it mainland areas or any public LL owned ones to actual mesh instead of sculpties or prims from the old days. The mainland is filled with those places, they lag horribly and are mostly deserted.
SL also needs some serious cleanup and do something about the traffic meters. Right now the most traffic goes to places with AFK adult sims, where people sit around on furniture and get tipped from sexual activities or places with bots everywere. Traffic needs to be redone to monitor how active people are instead, by moving around, chatting, or voicing.
Also the marketplace is filled with junk from 2008 - 2010, still sold at full price, old scultpies, laggy scripts and so on.
