I don't really know what to think of the bots, if I'm completely honest. I'm still pretty new and learning as I go.
I have now used a couple of bots for 2 of my blog posts, which I deemed to be of enough quality to get them noticed a bit more.
Not sure if I will continue to do that in the future, if anyone would give their input on the matter, that might help me decide...
I'd say you should keep trying to build your audience. I see you went to Fosdem. There are plenty of open source fans here. I know @dickturpin has been saying there didn't seem to be the same audience for that sort of content here compared to somewhere like Google+. Maybe that can change
That's what I'm going to do. Besides, I think it's better anyway to keep investing into getting more Steem Power anyway. A higher value upvote on my own blog posts seems a lot better than using these bots.
