The thing about "tags" and DIY blogging is that all the tools treat "tags" like "categories," so you'd expect to have 1, or a handful. "post" or "photo" or whathaveyou. But I treat "tags" like a teen on tumblr. hundreds of nonsense non-sequiturs, follow-on jokes from the post text, and so on... the giant blob of data that Eleventy puts together when it builds my blog is beyond enormous, because all those 100s of values end up on all those 100s of posts.... It still builds pretty fast though, so I guess it's fine?
