I have never really used Flash for anything. My attitudes and knowledge of it all stem from experiences gained around 2000. When I read Dan Webb's post about how he was going to start to learn more about the newer versions of Flash, I had a kind of smart-aleck response: Ya sure, if it runs under X Windows on Linux.
But Dan has a lot of comments on this post.
The comments point out that these things are never as black and white as that. Theres a lot more to this subject that I don't know about and his commenters provided even more links to read. They definitely add to the value of Dan's content.
I regularly encourage new bloggers to encourage comments, and respond to comments. I encourage readers to make comments where they feel they can add to the discussion.
