Ripose,
Don`t worry I`m still here for the original intent of the thread.
For search engines a domain name can`t really be too long. However, for your user it can. Even though there is a huge benefit to having a short + keyword domain name your ultimate goal is to make it relevant and memorable to your user.
Customers or users will have a hard time remembering your site and doesn`t create a brand.
So there is a fine line between branding and valuable keyword domain. Sometimes you have to do a mix, abbreviations or think of descriptive words to make combinations that are short and memorable.
