I have been using a number of condenser for steemit and I am using a single account,

I only use them depending on the content that I was making

1. steemit.com -when I upvote and sometimes comment
2. musing.io -definitely here, when asking and answering random question - I just found it today
3. d.tube - when I was uploading videos
4. busy.org -like steemit.com I use this when I upvote and sometimes comment
5. ulogs.org -when I make my #ulog post
6. esteem surfer -when I make my newly come up challenge to myself #dailyquestion , been using this for a week
7. esteem mobile app - when I make post when I am not at home
8. steepshot - when I suddenly capture an image and I want it to be published in steemit
