It's a duel purpose group. I just joined and got my first feature in the daily newsletter that indeed got me some extra eyeballs. The bot also upvotes one post a day with a trail of about 30 members upvoting you as well. altogether it's worth about 0.25SBD.

As coincidence would have it I'm working on a post about posting strategy that I should have up tonight. I'll come back and drop a link to it here when I have it posted it. The very best way to get more views is to get your post at the top of the hot and trending list on as many tags as possible for as long as possible without being a tag spammer.
