I currently use Actifit and never thought of using an alt as it felt like part of the experience is to share with the community the journey within the ecosystem.

I think it is part of the experience but, once you start to roll in content from 20 different applications that do similar and what is 'real content' starts to get drowned in ones own activity. I don't think it should be that way but without a decent sorting set of tolls it will be, especially if Steem does what is promised and keeps decentralizing through apps.
