Amalthia's recs and fan works

I do like my HanLin! I mostly read mobi and rtf. Mobi works well, and rtf is so useful - no matter the size of the original font it is readable on the reader, unlike doc or pdf - which I've only just discovered, to my chagrin. I used to up the font size on rtfs assuming I'd need to to be able to read it well. However, large fonts are just ugly and annoying (you have to change the page more often), especially when it turns out that 9pt verdana is totally readable without magnification! My only experience with ePub is the one I have on my reader that just will not open.
