Like the title i think this is very interesting because i am rare to see long url in the top position search engine
disagree - i have a domain name that is 21 letters long and is on page 1 of google on some very big searched phrases ! dont think the length makes any difference other then there is more chance the end user may type it in wrong.
I disagree as well. remember there was a site www.abcdefghijklmnopqrstuvwxyz.com and it had no problems ranking. A domain is a domain....
Yup - I too have a longer domain that out ranks others. Actually I wouldn't know what the definite answer is. I think as long as your site is built well and is structured correctly you should be ok. Although longer names are harder to remember/ on the eyes...
