Yeah, I have multiple accounts. Like you, I have a "main" account (this one), which is used for most of my content. However, I also have a separate "alt" account for my artwork, because a lot of people who follow me would have little interest in my "art journal" about ideas and work I am in the middle of. Our cats also have their own blog because I don't want to bombard people with cat photos and cat tales. So that's three accounts. But as a subset of the cat blog, we also have the "Hive Cats" community, which has an account attached. My wife has two accounts, one personal and one for her non-profit. As a joint venture, we just started a community about/for labyrinths, so that's one more.
Sometimes it is hard to keep up with, but it helps that the "alts" have very specific purposes. It's not a big deal, really, as I have kept "niche blogs" elsewhere for better than 20 years... at one time managing as many as 14, concurrently.
I also want to make quite clear that I have multiple accounts not as a way to "milk the system," but out of a semblance of consideration for readers; and as a way to serve "grouped" content.
