The original tvtome.com was everything a TV watcher could ask for: Simple, clean web site design, easy to access episode information, user forums, and so on.
Then mp3.com/Gamespot bought them out, changed the web site name to tv.com, threw in a bunch of gratuitous Flash, graphics, and ads, changed the episode numbering system (making it almost completely useless), removed the user forums, made it a lot harder to navigate the site, and in the process of all of these "improvements" also managed to make the web site reponsiveness way slower.
Luckily, I've found a replacement: EpGuides.com. It's not as full featured as TVTome was, but it's got the part that counts right, and I'm a believer.
Here's proof of what I'm talking about: Battlestar Galactica info on tv.com and epguides.com. Let's say you just want the episode information. Which one does that job better?
