Post History

I have a growing non-fiction blog about challenging existing dogmas in my culture, and it has been attracting a good amount of readers. However its growth is still not optimal, as they just read or want to meet me, not really commit to help me. I don't want to be greedy or arrogant, but I think I can ask them if they can help me in some tasks, so that they can see the project growing, and I can have time to focus on writing new articles. I sincerely consider me as being overloaded right now. The tasks they may help includes:

- Share it to other potential readers, either on their Facebook wall or via chat 
- Help me engage with other readers: manage pages, posts, comments
- Write emails to other targets: publishers, people they don't know personally but probably see its importance in their work

My questions are:

1. Is this reasonable?
2. How should I approach them?
