Small Tip:
--Have a friendlier URL for users. I.e., If I want to share my list with someone offline, I'd prefer to say, "Hey checkout 7bks.com/user/steamer25" rather than "7bks.com/user/1094004".
Yep - I know I should do that. Brings with it a few issues but I'll try and migrate over at some point - same with blog posts, I'd love to use slugs rather than numbers.
