Restricting search results to reddit is still a nice way to filter out corporate junk and just get honest end user opinion on things. As much as I hate the management of the platform now, you have to remember that Reddit didn't always used to be shit. Aaron Swartz was a co-founder.
Except companies have learned the meta, and now a bunch of search queries for Reddit are filled with ads on Reddit. (not to mention you have to use google to get their results now.)
Eh, I still get Reddit results through DDG. They may not be fresh, but they seem to still be in the index, and honestly, that's fine because I only really care about the older content.
