Can't remember the end of a cliche or whether to say use or used in a sentence?
Want to know how common a last name is?
Netspeak is a simple free tool I just found. Type in something like:
Winston tastes ?
music soothes the savage [beast breast]
and it searches a bazillion pages and shows you the most common matches for the question mark. Not the right answer, of course, just the most common one.
