Happy 10th Anniversary! I'm not much of a chatterbox, either on or off the Internet, so you won't find too many posts from me, but I highly value this site and would greatly miss it if it were gone.
I visit often, and I seem to spend a lot of time on http://www.mobileread.com/forums/forumdisplay.php?f=26
. I also follow the posts in Week's Hot Topics of the main page with great interest. I have looked in the Ebook Readers forums for my specific (Nook, Kobo) devices a couple of times when I was having difficulties and found solutions. Sometimes I just like to wander around and see whats here... this site is huge! I don't have any specific suggestions for improvement; everything seems great to me.
