Comcast sucks schweaty monkey bung.
From shafting their customers for every last penny (Oh look, my modem rental fee has gone up again on a modem they refuse to sell me), service that bites the big one (my tracert's show that my signal goes over 200 Miles out of it's way before coming back to make the ~50 Mile journey to the nearest Internet BackBone in Silicon Valley, and Comcast "can do nothing about it" even though I end up dropping signal from the 1 Full Second ping times), and "Customer Service" that goes so far beyond mere Unprofessional that it makes Cerberus look like a cute & cuddly puppy by comparison.
If I had any *real* competition in the area for broadband internet service, I'd ditch Comcast so fast it would make their head spin (a good trick given how firmly up it's own ass it's wedged), but when my "options" are paying AT&T to upgrade the copper to my house so they then overcharge me to provide mere DSL, or pay Verizon for a cellular modem & data plan that will rape me for every kilobyte they struggle to throttle my way, or the OH so lovely satellite providers that tell me I'll need to cut down my neighbors' trees if I want a clear signal...
And Comcast wants to merge with the Second Worst cable company in the nation, as if the "MegaComcast" won't STILL be The Worst Company In America?
Someone please take Comcast out back & put a bullet through it's head. We don't let feral dogs last this long, so why should Comcast still be wasting our oxygen?
