There is a lot of drivel, along with irrelevant, poorly worded, questions, statements where the authors expects us to be mind readers, gibberish questions written in text speak and other forms abreviation; and ambiguity where the reader expected to know what subject the author is referring to.
I answered an ambiguous question recently, the author asked about 'umbrella terms' so I answered using the terms required to refer to the use and mechanics of umbrellas. Apparently this was wrong, the questioner asked about 'umbrella terms' obviously I was thinking of different terminology than the questioner. I wonder what 'umbrella terms' are? :-)
