What’s missing in Twitter

One user tweets in multiple languages, merges business with personal
More and more users are starting to burst tweets. The bad thing is that many of them now switch from one language to another (I’ve done it), they switch from personal to business or from business to personal (although my twitter account is business, I’ve also tweeted some personal opinions too).
Loosing listeners
I don’t have the statistics under my nose (although it would be nice to get a response from twitter), but I guess it’s somewhat natural for users to lose their audience when they start doing the above. You’ve got your fan base listening in English. Then you tweet something in Romanian, German or Spanish. Although the tweet is on the same topic you’ve used your audience with, its very likely that you loose some of your followers if you start doing this often.
Geeting more followers
A nice feature that would solve this issue would be similar to Google’s circles in Google plus. One user has one account and multiple subaccounts (think of them like follower circles). This way tweets in English and on primary subject could be kept on the main account and followers of that account would get the info you share. Tweets in Romanian, German or Spanish on the same subject would be sent on their respective Romanian, German or Spanish subaccounts and only the followers of those subaccounts would get them in their timeline. You could also add a rant section, a personal section or whatever you want.
The above features would allow concentrating all your followers under one big roof and keep things simple. Currently, if you want to achieve something similar you’d have to create multiple accounts for each topic or language, switch between them and so on. A complete mess.
