For those who care about lesbians
(People who do not understand what I am writing about can safely skip this post.)
The major difference is that the first post was a good faith attempt to provide information which some developers believe to be important and relevant and some others do not, while the second one was a deliberate posting of obviously off topic information deliberately constructed to be offensive.
People who fail to see this difference urgently need a reality check.
If it was a way to make a point (instead of just a way to be an asshole, which is what a repeating pattern showed by the author would suggest) then it's quite a lame point since every developer should know that we all can post to d-d-a, and it hardly justifies an abuse of the list.
