the replies here are more or less like what I expected, dot biz is picking up. this is as well the feedback from our campaign for hosting.co.uk where we give away a couple hundred free .biz domains. People really like it and start using it.
We targeted startups and people with ideas, just the space for presenting the idea was missing.
so we gave them the domain (.biz), the hosting, and some microsoft exchange accounts.
And out of the sudden they decided to build an online presence for their idea. I think it is a positive feedback when startups start using a niche TLD.
I called a few and asked them if they would decide the same if I had send them a voucher code for one of the new TLD´s, the answer was really surprising, they did not know about the newGTLDs and believe they would have been confused what todo.
At the end, what I learned from this campaign is that, to convince somebody to build an online presence and start using the domain it must be a trustworthy established TLD. We will see next year during the renew if I invested my money well and the clients stay.
I will check on monday if I have a few codes left, PM me if you want a .biz and let me pay for it. but you must build a little site.
