1 - "bumping" a topic is so it can go back to the front page. Most likely a new volunteer will be able to see it, not when it's on page 6 of the forum lists. And I don't see why someone would purposely ignore it just because I "bumped it too much". That just shows cattiness amongst adults.
After you bump, I never see your post. Particularly, when I'm browsing these forums for questions, I use this view: http://wordpress.org/support/view/no-replies
Once a topic has a second post, it goes away and I (and many others) never see it.
So, don't bump. If I find bumps, I'll remove them without a second thought, mainly to get your post back into the views people actually use. Not everybody is looking at the "front page". Most knowledgeable people on these forums don't, in fact.
2 - Don't be so quick to assume. Just because someone else ended up helping me, doesn't take away from the fact that I still needed help. It may have took that person, and myself, hours to figure it out, where has here, it would have took an hour maybe?. Also, having someone else help me could have had a monetary value ($$$ per hour).
If you need help within an hour, or even a day, then this is not the right place to do it. People do have lives, you know. I check these forums maybe twice a day? Three times at the most? A 2-day response time is not unexpected when you're asking on a forum.
Secondly, yes, time of people often costs money. The fact that you can't get the same level of help for free is not really surprising.
In my opinion, being redirected to WordPress Codex, Google or getting ignored simply doesn't cut it.
Time is the key factor here. Most people don't have a lot of it available. So if I or somebody else simply gives you a link, then either a) the information you want is there, or b) they *thought* the info you wanted was there, even if it was not. Posting just a link is not supposed to be insulting, it's supposed to be quick. Most of the time, a simple link to a search or to the codex is enough to answer the question.
Never add your new problem to somebody else's old thread, even if the problem is the same one or you have questions about the solution. It's not likely to get noticed that way. Create a new thread and link to the old one in your post.
