Why offer .DE?
In terms of registrations, .DE is the most popular of all ccTLDs and ranks second after .COM among all TLDs. It is very popular in Germany.
.DE is also becoming increasingly popular 'domain hacks' in Romance-language (e.g. Spanish, Portuguese, French), as de means "of" in these languages. For example, http://elforo.de/wikipedia effectively translates to "http://theforum.of/wikipedia".
