First, it would be quite strange if there was a lot of threads like "Everything works fine, what to do?" "App installed perfectly, shall I use it now" etc etc. If things hum along fine then you don't need help do you? So forums tend to have a big amount of help-threads. Secondly the same applies to apps, you want some- you ask helpfull people.

I don't know how your operator works but for me weak signal means that I am far out in the countryside or inthe forrest, where, frankly not much is happening anyways...
