This might not be the most appropriate/best way of letting you know but I couldn't figure out how to send PM's (sorry!).
I was on ESPN reading some college bball articles during lunch, and saw their blog roll for SB Nation sites. I picked a random article, but you'll see the blogroll on the bottom right (random article)
The link that ESPN has for the BN Bball section is incorrect (maybe outdated?). They have the permalink structure as www.bruinsnation.com/section/basketball, whereas the correct structure is www.bruinsnation.com/ucla_basketball (parts in question bolded). It sends the visitor to a 404 page (and it does have a link to the BN homepage) but things like this are shown to turn off new visitors.
Not a crazy big deal but still something that should be rectified, I think. I sent that support email a message as well but thought maybe someone more responsible than me should email them and stay on top of it as well.
