>> "I've been using Tumblr for years and I still don't know how to directly comment on someone's content without reblogging it" I think reblogging doubles as a commenting system. If you look at the original version of the post you reblogged it will show that you reblogged it with your added commentary. Most themes also make it easy to add Disqus just by adding your Disqus site name. There is also the 'ask' feature which allows for more direct user interaction, and I believe there is an option on one of the post types to pose it as a question and allow users to respond.
