I saw this article pointed out on the SL subreddit... I'm not familiar with 'Document Journal' and presumed it was just some 'wordpress' level self-publishing dropbox. I stopped reading when I got this:
Second Life is vehemently no-fun to play, in equal turns boring, frustrating, saddening, and brutal.
I tried again because it showed up here. And stopped at the same point. If that line was presented as an opinion, I might have kept reading, but it wasn't. The author's tone delivers it as "Fact". no thanks.
Two decades of seeing criticism about SL, and "Projection" seems to be a very core theme to a lot of it.
SL is what you bring to it. It's a creative world if you're a creative person. It's a social world if you're a social person. It's a sandbox if you're a tinkerer. If it's boring, it's probably because you're boring and lack the motivation or attention span to find something interesting to do with it.
I get that the learning curve may seem daunting and infinite, but same is true of real life too. The consequences of 'logging out' of RL are a bit more permanent though, so we stick with it, even through all the 'no-fun, boring, frustrating, saddening and brutal' parts.
