Don't flag it modlook, please. We're here, we know ;) No need to spam our RSS feeds.
you encourage that people search for their answers before posting it again, which assumes that they'll find an old post with an answer.
Well not a post, but a something, sure. Given the number of times we can solve a problem with a copy/paste from our notes proves that they don't search first.
But you're not asking about user stuff, you're asking about SUPPORT stuff.
I don't recall deleting any of your posts in the last week, but I was also 'off.' Because of that, I can only offer you some basic and general advice.
If the majority of your posts are a link to your plugin, it's a sign that all you're doing on the forums is promoting your self. This is because if you were intent on helping people, then the implication is that you are more altruistic, and you would mention other, similar plugins (Widget Logic, for example). Alternately, you would question for details.
In this post, someone wanted two different sidebars, one for the start page, one for the blog page. You didn't even ask 'Are you using a static front page?' Also, the person said he was WORKING on a theme. Is he writing one as a developer, or editing as a user? You don't know. So if your goal is to help people, you ask.
If your goal is to support your product, and here I should emphasize there is NOTHING wrong with that, and I laud anyone who takes the time to do the thankless job of supporting their plugins from the ingrates (of which there are many), then what you've done is self-promotion, and that's just not nice. It's not horrible/evil/bad, but it makes you look like a jerk, which I'm certain is not your intent at all!
I really hate perception on the Internet and how easy it is to screw it up :/
