I'm mainly keeping an alt account for /r/SQL because for it's sort of a defacto professional repository (also the only place you can ask for and get a sciprt for a bespoke data cleaning on a large relational DB in about 60 minutes).

I do get deleting accounts (and I'm deleting my "main" just commenting account) but some of the accounts have literally irreplaceable info, not just in the tech space, but my god some of the guides for gaming in older games only exist on reddit (like getting a full 50 monuments in the original Guild Wars, or setting up a good build for Bioshock 2). So I'm keeping my "info" accounts for as long as I can, I know it adds value to reddit being assholes, but I feel it adds more value to a stressed out Admin over their head in a bad situation, or some frustrated retro gamer that doesn't want to know the glitch mode that everyone uses right now.
