I think I'm happy with the outcome. People were always looking for an alternative to Reddit and all that was missing was critical mass. Now the alternatives are totally usable outside of small niches which will catch up eventually.
Reddit is definitely shitting its pants. They used to have zero direct competitors.
I think multiple accounts is a great idea.
I work in tech security and I cringe in pain when I see people post their 10 year accounts. The amount you can deduce and learn from mined social media data is absurd. I migrate to a new account every 6 months and that's the longest you should keep an account. This of course doesn't apply to your public brand account.
