these are some of the aspects that cause me to wonder if steemit will survive. i guess there will always be people with short attention spans. there should be a place for comments on "dead posts" somewhere on the profile page. i feel the same about accessing my old comments and replies. if they're are in the blockchain forever, why not? i've taken to saving significant comments and replies that are not on my posts. it helps me monitor my writing. i hadn't thought much about having multiple accounts. it seems like playing chess against yourself. could be useful.
