Yeah, I've always wanted a 'Creator's Picks' section, or something like "Other [this series] Readers enjoy these comics:", though that second option would require a lot more calculations pulling data from people's subscriptions and might cause a lot more problems of its own.
What I would like to see is the comic recommendation section have stuff in at least somewhat the same magnitude of popularity, like Smackjeeves used to do back in the day with its 'similar comics' section.
If a comic has <50 subscribers, but almost all of them are also subscribed to a series I already read and enjoy, then I'll probably like that comic as well(maybe even more so than whatever's popular sitewide.)
