The one thing that is interesting how quick I started getting spam comments like the ones you mentioned in your post. I'm about a month into Steemit and I get an occasional comment that makes zero sense to what I wrote in the post.
I wish that Steemit had a way of saving favorite posts in a folder (like this one). But I'm not sure if it's feasible.. I'm not super knowledgeable on blockchain outside of the ted talks I've watched and content I've read online.
I agree - I've only been here 4 or so days, but already there are couple of post (similar to this one) that I feel like I'm going to want to come back to...a 'favourites' list or something like that would be awesome.
