The biggest difference between LIMIT and truncate() is that you can put truncate() at the end of a series of other pipes.  Implementation wise they are essentially identical. For example:

select * from search.web(100) where query=’yql’ | sort(field=’date’) | truncate(count=1)

Which will find the oldest search result in the first 100 results.
