Welcome to the Q&A Forum

The one thing I would add to your list of criteria, if you choose to go that route, is to look at Google Analytics landing pages and make sure the individual profiles don't any inbound search traffic.

This is totally down to a matter of personal preference.  I'd be looking for something in the way of original text.  A good way is to ask more question then total up the number of words in their answers.  You can also flesh that out by introducing snippets from recent activity, connections etc.  Do though try to include something in the way of original content in order to turn off the no-index. I think your example isn't bad.  Add a personal slogan, or line of introduction and it is probably enough.
