I have the same conundrum. I don't know when to post something to my blog, and when here. I try not to have any cross-polination - for no good reason at all whatsoever.
Typically it breaks down by topic. Everything about cryptocurrency I post here. I've written a few Apple posts here, too. But hard-core technical stuff, I post to my blog. I guess I kinda feel like that's my "Here, I'm an Internet Person, if this helps me get a job then that is very good" site.
Whereas here I post stuff that's weirder or more philosophic or more rambling. Or "might be boring to people who know my blog," maybe?
I'm still not sure.
