What it means is that the answer is both factually correct and complete and that people who wanted a serious answer look no further -- i.e. no need to click through pages of drivel that follow. If you only see +1, it indicates agreement but leaves open the possibility that more answers could follow.

In the case at hand, I could have mentioned the possibility of the tire being defective, but the question was whether there is a usual cause (there is, and it is common). If the tire were separating, this would be obvious as the poster was wondering if something as subtle as a little soap residue could cause the problem (it won't).

Since there are obviously a few people who aren't familiar with the dynamics here, I'll explain how things work.

The most important thing to know is that for this place to stay healthy, everyone must both contribute and benefit. People who want advice can learn about gear, mechanics, training, where/how ride, and a number of other useful things. People who have a basic grip on these things hang out for entertainment.

This place can't just be a place to deal with bike problems. First of all, pretty much anything you can ask has been asked and answered many times (even this discussion about perceived elitism pops up regularly). There's only so much you can say about gear ratios, wheelsets, bearings, basic training, etc.

People who basically have their minds wrapped around this stuff need an incentive to stay so you see a lot of useless chatter. But make no mistake -- that is the lifeblood of the forums because without it, this place becomes boring and people who know what's going on leave.

It takes all types to make this place work and we all have a little fun at each others' expense. But if you stick around, you'll occasionally find nuggets. Just be prepared to sift through the other 99.999% which is crap.
