Frontier Communications has added a download cap to its Internet service. It will charge folks for heavy usage.

The company caused confusion and some dismay among customers earlier this year, when it said it would charge for Internet use above 5 gigabytes per month, starting next year. [tbo.com]

What's most interesting is the comments. People are not happy about caps.

Caps are not new. We had time limits in the dial up days. (When you can only access at 33K, time is the limiting factor.) Satellite has always had bandwidth caps on its Internet service. It will become more pervasive as revenues for ISP's decline in this economy.
