The Anti-Spoiler Plugin
So, in fear of reading information about television shows on the web, I am in hopes of having a Anti-Spoiler Plug-in (something that I talked about before). You could select shows and the choose to censor information from an array of options. For instance, you could have it so it blocks ALL information about episodes you haven't seen yet and future episodes.
How would it do this? It could look for words like "season," "finale," along with the name of the show, or maybe the name of the episode, and then some intelligent programing to display a dialog like: "The following page has information about the show Lost that you have optioned not to view."
Also, the Spoiler plug-in could be extended to include other things, such as protecting against spoielers of Apple announcements.
