It's getting better (Score 1)

I spend a lot of time on public transportation. A couple of years ago when cell phones were still new and people were learning how to use them, the problem of loud talkers was really annoying. However, I have noticd that the problem seems to be taking care of itself as people learn that they don't have to yell to be heard on their cell phones. They use of the phones has increased, but people are using them much more sensibly and keeping their voices down. Radical solutions like jamming the phones are becoming much less attractive.
