Considering Tumblr and Other Questions

A friend of mine asked if I was going to post my chapter updates to Tumblr as well as to Wattpad. I'll admit I spend very little time on Tumblr these days but many of my friends and followers are still super active, and I know a lot of writers, though primarily fanfiction writers, who do post updates there and get a lot of feedback. Any Tumblr users out there who like the idea?

Also, while I already have a lot of ideas in mind for the weekly blog posts that will accompany the chapter updates, I would love to hear from y'all what you'd like to see. Anything besides background on the books and on writing, book reviews, and so on? Let me know!
