The Lisp Curse
Interesting read, that resounds with something we were talking about at last Haskell meetup.
Lisp is so powerful that problems which are technical issues in other programming languages are social issues in Lisp.
Consider the case of Scheme, again. Since making Scheme object-oriented is so easy, many Scheme hackers have done so. More to the point, many individual Scheme hackers have done so. In the 1990s, this led to a veritable warehouse inventory list of object-oriented packages for the language. The Paradox of Choice, alone, guaranteed that none of them would become standard. Now that some Scheme implementations have their own object orientation facilities, it's not so bad. Nevertheless, the fact that many of these packages were the work of lone individuals led to problems which Olin Shivers wrote about in documenting the Scheme Shell, scsh.
