A couple years back the answer for me would've been Google. These days, I really wouldn't mind if Google went away, but I would really miss reddit. My use case for Google is mostly as a reddit search engine anyway.
EDIT: I meant Google Search only, not the rest of Google.
Google and it's not even close.
Reddit is a good way to connect. But it's social media. There's lots of players here. Reddit's strength was the (false) perception that it was 'one of us'.
Reddit (via /u/spez) made it clear that they'll step over their users. They made it clear that to engage in conversation with them - you need everything well documented (and recorded). They feel dirty to me now.
The users made reddit. Seems like many are headed to the fediverse. It may never have the numbers reddit has but it seems destined to carry its spirit. See you there...
