If you’re not following the blog of author August Wainwright (first: why not?, and second: you should!), you may have missed his Indie 50 list, the fifty best sites for indie and self-published authors. What you’ll find there is a wealth of resources that’s truly invaluable.
The list is both searchable and fully sortable. You can sort by rank, alphabetically, or by category. There’s quite a bit of overlap for some sites as far as categories go, but I’ve attempted to put each site into 1 of 5 categories :
Self-Publishing, Writing Process, Resource, Social, and Industry/News.
Read the whole blog post to see his reasoning and criteria for the list, and make special note of item #25.
