Do I think tiered Internet is a great idea?
No never have.
Do I think throttling iTunes is a good idea?
Do I think metered bandwidth is a great idea?
If done right, yeah. In other words, I don't have a problem with paying more for more usage. I do have a problem with outrageous rates or degradation of service I pay for.
Starting on Thursday, January 31st, Time Warner subscribers in Texas starting experiencing connectivity issues to the iTunes store to the point where the service wasn't usable. General internet traffic issues haven't coincided with these problems, and many folks have reported that the store works as normal when they head to the nearest mega-bookstore and use their ISP instead. Time Warner has announced that they're going to begin trials of tiered pricing in one local Texas market, but I'll be darn sure to switch my provider if I hear the slightest hint of destination/content based tiers instead of bandwidth tiers."
Still think it's a great idea, Tom?
