Well, we have new neighbors. They seem like nice folks, younger people, and I noticed they are using a Wi-Fi connection for their Internet access.
I noticed this because it's open and shows up, with a very strong signal, on my Mac's Airport.
I also had noticed a truck from Charter Communication was there when the new folks moved in.

Here are the results for Charter cable:

I see no reason to change ISPs.
