Sorry to create a spot of bother.
The changes to the title and firstwords at the top are designed to let the search engines know what the threads are about. People don’t naturally write so that the search engines can find the threads - ie actually saying what the threads are about in their first sentence. So the firstwords actually use the title and repeat it - have a search for anything and you will see that Google highlights the first several instances of the search phrase.
Along with other enhancements, each thread will actually start ranking on the search engines for their title, whereas before they would not exist at all.
More people able to find your information, more community - I know you are big, but why not be twice as big.
