Twitter is too loud/busy. Having to post every 2 hours on Twitter is much more difficult than posting 2 times in 24 hours on Instagram. Also, Twitter has become WAY too strict. The only way I can see Twitter being beneficial now is if you have 10-15 accounts following a maximum of 150 people per. day. Age of the account doesn’t seem to matter anymore and neither does warming up an account.
I dunno, having a P.V request from Twitter every single day gets really annoying after a while, it’s why I stopped trying to grow my Twitter accounts and started to just maintain the follower base I have built up across my accounts.
