Raymond Hackney published a relatable article about “Domains Wanted” posts on NamePros. I think the commentary would apply to other domain forums, Twitter, and on other venues.
I have posted a few threads on forums and even here on my blog, and my experience has been similar to what Raymon wrote for the most part. I would often receive domain name submissions that are totally unrelated to the ask or the prices are not where I requested. I try to be very specific about what I want, but it’s difficult to do that and keep it open enough for good domain names of interest.
I did have a good experience a couple of months ago when a domain name wanted tweet resulted in the purchase of Cappuccino.com.
Have you had success buying a domain name after publishing a “domain wanted” post? If so, where did you post it and what did you buy?
