Yes that would be nice. I thought that this weekend i will try to implement the new improved profile feature. This will enable the user to also see all stories the user has submitted to DNK. I will also enable to change password.
If a DNK user doesn't have a Gravatar account, what's the worst that can happen...they're assigned a default avatar? Seems like a pretty small price to pay. On the other hand, users with Gravatars (disclosure: I'm one of them) have yet another site that supports their online 'branding'.
Gavin, I say go ahead with it -- the time it takes to add support for custom avatars will probably be better spent on other DNK features. monty is prudent to be wary of a third-party solution but I really don't see much of a downside.
i've also seen gravatar sllloooooooow down sites. @cdjaco - i kinda see what yer getting at in reducing complexity and dev time...but i could also respond with "why not just use digg instead of DNK"...essentially what yer saying, since digg has more features and it would save gavin and the dev team the dev time.
monty: I wasn't aware of a Gravatar-induced slowdown. I understand your point about Digg, though I think DNK is far more useful since it doesn't have the swarms of partisan morons turning every item into a political debate.
Anyway, I came across a potential solution to the Gravatar speed problem: http://troubleseeker.com/2006/12/15/taming-the-gravatar .
