Ask HN: How do you Deal with Multiple Identities?

Today when cementing some things with my new company, I'd realized I've amassed quite a few Google Accounts -- personal, my company, and someone I consult(ed) for. There's also the current day job's whole communications suite and everything that comes with it.

I'm not so concerned with dealing with the amount of incoming signal or noise, but what I'm curious about is have people who have defined who is the "work me", "personal me", or "work me #4"? Or have you done what I've done so far and kept it to a single silo?
