To me, one of the best features of the .tel domain name, is the ability to "click to call"... You arrive at your destination link, click it, and the call is placed... This is revolutionary to me, the applications for mobile computing would seem endless using this TLD...This is the reason I've registered about 15 TEL domain names in the past week...
When .tel first came out, I thought it was just another .travel or .aero...... Then I did the research, and realized this TLD is very different from anything else...So, I searched for the best names available, and came out with some decent ones... When regging, I always try and make sure that the keyword fits this ext, I think that's more important with .tel than any other extension, even .org...
I think in the next few years, the huge phone companies are going to be investing some serious money into this TLD, and the global possibilities are staggering if this happens....
Prague.tel might just be the beginning of something big, I just wish I had started investing in this TLD when the really good names were available... I remember getting notices from Dynadot during the sunrise, and landrush, and I completely ignored them...But, it's not too late, as someone pointed out earlier in this thread, there are still some decent names available, you just have to dig hard to find them....
