Later today (its 8am here) I'll be publishing the weekly #stewardsofgondor post, and this should give you some clues as to the level of activity and interaction that the Stewards have undertaken during the last 7 days.
The key when starting out is to seek out the accounts and content that you have a genuine interest in. This will give you the ability to write relevant and interesting comments, which should in turn drive people to your Posts of a similar nature.
Upvote your favourite posts of this nature, and be sure to vote up the best comments on your posts, (I try to scale them in order of quality) - this is a technique to try and retain visitors.
Finally, your posts need to show effort/interest each time (as the one above does) as consistency is a good way to pickup and keep the followers visiting.
I hope this is useful to you, and hope to see some interactions with the other stewards and beyond in the coming weeks. Cheers!
