Alone by itself, you're probably right, it doesn't matter. But there has been a lot of stuff talked about on this site and it doesn't take a genius to compile all the info together to help whatever group the guy who is looking for this info is working for. I'm guessing they would like to collect whatever they could. They may like to know the cost of fuel, b/c maybe it'd be a smarter move for a terrorist group to bomb our fuel depots rather than a civilian building. It would drive the cost up as well as limit our capabilities.
My point is, alone by themselves, the things mentioned on this site are relatively insignificant. When you put them all together though, in the bigger picture of things...they may be a bit more important.
And no offense to NSFW, but just b/c he's been on this site for a long time doesn't mean he's not spy. It doesn't mean I'm not a spy, nor you, nor Toro, or anybody else who frequents this site.
