Well, reposting and liking is 100% available when people see your posts on their dashboard. Commenting is also possible as long as you have “allow replies” set up on your profile.
If you’re asking me how to generate more traffic, I don’t have the answer to that. I really don’t like the self-promoting taglines seen on some blogs. I’ve never done any of that, and got lucky enough to gain followers based on what I believe to be quality of posts. (Everyone’s taste varies on that matter though.)
Good luck! —sbb
