Well yours looks pretty comprehensive. I think a good profile fits the type of reader you are hoping to attract, or the type of writing you are offering.
So there's no one answer, but putting a little care and effort in is worth it. It's very much a shop window, but it doesn't neccessarily need to be be packed full of stuff.
Someone reads one of your pages and then maybe checks out your profile. Will they read some more, visit your webtsite, or something? Then that is a good profile.
