I'm sure everyone in the Buffy fandom knows this one, but I've spent a lot of time on BuffyWorld researching for fanfiction and episode analysis. They've got the shooting scripts for the entire series in addition to the transcripts - I've actually gotten stuck there just enjoying reading them and finding where they differ from the aired version.
For MCU canon-checking I usually head to the Marvel Cinematic Universe Wiki, which covers most of what I need to find out. I'm not crazy about wikis but, like Tumblr, it looks like that's what's in these days. If anyone has any other MCU resources I'd love to hear about them!
I do my squeeing, for the most part, right here. And let us never forget Blood Roses and all the happy times it's given us B/A shippers.
