I usually agree with TimBL on everything, but not this time.
New or newly popularized TLDs represent new business and cultural territory. Without this new territory, the consumer "domain name memoryscape" inhibits the adoption of new business and artistic ideas.
It might even be a good idea to make it as arbitrary as possible: every year, choose one random two letter and several three-letter domains. Then let creativity decide how to make use of .kfi and .iz.
Randomly generated TLDs are a brilliant idea. You unexpectedly make some set of people very happy. The problems come in (a) determining where to host the root zone and (b) if that name is later needed for something else (a new country)
At the very least, you get 26 new url shortening companies, and a stack of people with cool email addresses...
