I know this is not related to the new profile pages, but it does relate to changes at Github, and I was reminded of it by the "public activity" mentioned in profiles.
I'm still rather disappointed at the loss of a useful homepage. I used to have a stream of activity for repositories I watched there (e.g.: rails), but ever since stars were introduced, this is no longer the case. I tried watching the repository again (instead of just starring it), but that results in me getting emails that I can't stop. So I either have to accept that I'll get an endless stream of emails every day along with an updated homepage, or just have a homepage that never changes.
I appreciate the work going into Github, but not all of it is for the better.
I rather have the Activity feed as the default view and not the public repositories. Activity is far more dynamic and useful.
Now the activity feed is two clicks instead of one. Not a problem, just a slight annoyance.
I like the new profile pages, I think visually they're a nice improvement. Im not sure if I love the new activity streams yet. Do I really need a facebook stream in my github?
For 5+ years, Gravitar wasn't used for anything more than Wordpress sites so I picked my company logo (so I can respond "officially" to reader comments).
Now my personal github profile looks like the official company github.
