My dilemma right now... Litecoin or Namecoin? 

There will be more Litecoin in circulation which seems to cap its potential in a sense (at least when thinking in terms of OP), but Namecoin almost feels like a perfected version of the Bitcoin.

We've seen it happen before...

Yahoo -> Google

Myspace -> Facebook

Compuserve -> AOL

etc...

As the saying goes... "second is the best".

So who's on second?
