I still depend pretty heavily on browsing, but now it's at the library since for financial reasons I can't really buy books these days. I like libraries because I feel like I can really try new things and authors, and I've got a list of books I plan to buy when/if I have income again. If I did have a job I'd probably still do a lot of my browsing in bookstores, though, since I don't have (and don't want) an ebook reader. I've got lots of authors on my LJ flist and whose blogs I check, and I try to see who they're reading (in addition to paying attention to when they've got new books out). I'm also on Goodreads.com, so I can see what friends are reading--the "People who visited this book also visited X other books" function is turning out to be a lot more useful than I thought it would be. For nonfiction books, I check and copy down interesting-sounding books from the bibliographies in the back to look for at a later date.

I'm sure I'm missing things, especially since my library likes to shelve fantasy books in with mainstream while SF gets its own section (grrrrr), but I don't really feel like I'm having trouble finding new authors these days.
