When I first signed up I'd already been writing on a number of other sites that told people, "write anything" It turned out that I earned more money on here (with the revenue-sharing thing only; I'm not taking about sites that paid me a flat amount for a piece with or without revenue sharing as well). Even after the first big Panda I was still earning (less, but still earning) with the kind of stuff I had on here at that time but have since deleted in many instances). I pretty much abandoned those other sites because I could see that they eventually headed in a self-destructive direction.
I've been willing to ride it out here because I think I have a fairly decent idea of the kind of stuff that will get is own traffic without competing with what authority/specialist sites offer (even if that means staying with subjects that I, personally, can offer something a little different on, rather than try to compete "everything else that's out there on an authority/specialist site, and that's essentially some version of the same thing".)
Basically, and for now, I like how this site operates and see no reason to rule it out if I have something that I think deserves an audience and/or think deserves a place in search engines for someone who may be looking for something on a particular subject. These days (and after a number of years) I'm just re-thinking and/or re-organizing some things with regard to what I'll post on here from now on.
Having said all that, maybe the one thing that i find most encouraging in general (and after first signing up with "writing sites" about ten years ago when "everyone" said that "nobody cares about proper English grammar any more"; and when there was actually a certain amount of verbal hostility flung in the direction of anyone who dared to say that grammar still matters to all kinds of people) is that people aren't saying "nobody cares about grammar" any longer (or at least not on this site).
As long as official word is that grammar matters I'm encouraged, because I can take it from there with regard to figuring out what kind of Hubs to post from now on.
