Double Letters in Domain Name

Which is better?

[Jordo needs a drink]

When the end of one keyword is the start of another, creating a double letter, which is better? Deleting the 2nd letter, or keeping both?

Example:
www.blahhobbies.com
www.blahobbies.com

[Webwork]

IF you plan to be very popular website why not spend the few extra bucks and claim both? Redirect the typo to the real site.

If not, then take the proper spelling of the 2 words and let some typosquatter take the other. Feed a traffic leech today. :-P

Always use the real spelling, it is the standard practice.
