"The growth rate of additions to the BIZ and INFO zone files has slowed from approximately 1,500 to 1,000 names per day. Utilization rate (i.e. activation of live web sites) in these new namespaces so far is in the range of only
1% to 3%. "
The article is a little old but its still hard to beleive the % of names being used has suddenly jumped so much.
