I hear that Streemian is closing completely. That's probably going to put a damper in this Steemit project.
Streemian is just one tool of the many available. Look:
http://steemtools.com/If you want similar functionality try steemvoter.
I'm familiar with SteemVoter. It serves a different function than Streemian. What are you using for your trail project now?
I'm using a custom application that helps me save time, but I'm still reading each post prior to upvote and resteem with @devcoin.
Other than curation, the most time consuming part is to gather the list of members, since such data is not indexed in the blockchain, it requires to monitor all transactions.
If you have a custom app that functions more or less like Streemian, then I would be very interested in possibly using it for my own purposes down the road. What I like about Streemian is the ability it provided for other Steemit users to follow a trail. So for example, if you followed my trail, you could automatically upvote everything I upvoted (posts and comments). So, does your tool do that? If so, I'm very interested in it
