The only real solution I’ve found is to subscribe with some tags of my own (like “frugal”) and then see what other tags are often used. It’d be a heck of a lot easier if they’d get some categories/standard tags. I’ve seen at least three or four ways of tagging “personal finance” and it’s exhausting to have to do each iteration.

It’s supposedly the most popular bookmarking site. But I get the fewest hits from it. Probably because it takes forever to build up a network of like-minded people. Mostly, you have to (again) subscribe and see who else has content you like/that’s like yours. Then add them to your network and hope they check you out. Then hope you have the right tags to attract other people’s searches and subscriptions.
