Over all so far a positive experience with the platform, my opinions are based upon an incomplete understanding so take it all with a grain of salt.
Things I want:
Self curated streams with variable logic
Easier method to discover content
Easier method to learn the feature set
Streams, threads, or order more easily to organize my own postings
Things I like:
Ease of use
Low barrier to entry
Brilliant idea for a multi-user platform
