Count me among those who don't consider this to be worthy of "sticky" status. A good enough topic, but it can sink or swim on its own merits.
I hear a rumor - I panic. What will I do? Investigate? Maybe try "gas prices" or "fuel prices" in an Internet search engine looking for a source of reliable information? If I were to do so, I might find something really useful, such as
this nice page at fueleconomy.gov. Why, that could quickly get me to reports (including date, time, and location) of recent lowest (and highest) gas prices in my area!
No, I wouldn't do that - I'd just continue to panic. While panicking, I might just happen to visit the JREF forum. No solace for me there, unless I were to happen to stumble into the "Politics, Current Events, and Social Issues" forum. If I were to go there, I'd see a sticky telling me where I could go to get information to dispel just that sort of unfounded rumor. What luck!
I just don't see that scenario playing out. Those who are sufferering from rumors because they lack such information aren't likely to come here. Those who come here can find that sort of information on their own - it just isn't that difficult to find.
We could use stickies in an effort to make the visitors of the forum aware of all sorts of potentially useful information - some of which could quite literally save lives. I don't think most people come here, though, to see stickies about diet, exercise, health care, wearing bicycle helmets, keeping automobile tires properly inflated, driving defensively, driving for better fuel efficiency, etc. It's just not, IMHO, the purpose of the forum.
