Caleb is right in that loose lips sink ships theory.
For example, yesterday when I mentioned that some birds were moving in the northern plains, I said mention if your state is seeing fresh birds. The point being, it is a general location VS a specific one, and most will report in a very general way, but not specific places, like "I was SW of ABC City and there are tons of Mallards there". I would never condone telling people of specific places so as not to overrun the place like what to Caleb last year. I too have seen the ill results of big mouths when it comes to fishing, it went from decent fishing to boats galore in 1 weeks time because somebodies ego just had to brag where he was catching them
(I found out he bragged at the bait shop of all places :pissed: ) . Part of the deal is one should be scouting, whether it be hunting or fishing. Telling a trusted VG friend is one thing, but specific reports on the interent will just PO people that live/hunt/fish in the immediate area of a specific report. There are internet hunters who only scout using the internet gleening any info so they have a place to go where they think a concentration of birds will be. So I do not do specific reports for that reason, nor encourage others to either. General reporting of info is OK though and is encouraged.
As for the mapping, in theory it is pretty good, but I've seen such varying reports for the same state, you know some are purposefully skewing the reported #s. Then there is the highly varying standards of activity too. 1 guy seeing a flock of 50 Mallards and reports high activity, while another one says that is moderate while I would consider that very low activity compared to what I am used to. My point being is that there are too many variables of reports for it to be of much use for it beyond in the very general way.
That is my personal view of this, I'm sure others have their own view though too.
