sorted (WAS: lambda)

That completely depends on the objects in question.  Compare
   temp = all_posters[:]
   temp.sort()
   top_five_posters = temp[-5:]
to:
   top_five_posters = all_posters.sorted()[-5:]
which became possible only when .sorted() was added to Python 2.4.
I believe you mean "when sorted() was added to Python 2.4":
py> ['d', 'b', 'c', 'a'].sorted()
Traceback (most recent call last):
  File "<interactive input>", line 1, in ?
AttributeError: 'list' object has no attribute 'sorted'
py> sorted(['d', 'b', 'c', 'a'])
['a', 'b', 'c', 'd']
Note that sorted is a builtin function, not a method of a list object. 
It takes any iterable and creates a sorted list from it.  Basically the 
equivalent of:

def sorted(iterable):
    result = list(iterable)
    result.sort()
    return result
