Except that the resulting rendering is an image so you can't copy and paste. I suppose some content providers will consider that a feature, but as a user it seems like a serious bug to me.
The SWF in the article were two snapshots that I overlayed, one from Flash, one from Word, so it has no interactivity with the curser.
Truth is, it's entirely possible to enable text selection, if that were a real demo of the text engine.
There's lots of other reasons not to use Flash, namely that its slow for lots of text, and it doesnt display anything at all on the iPhone and other mobile platforms. Using SIFR to replace headers is OK, but beyond that, I still hold that using Flash for text (on the web) is bad form.
In hindsight, I should have used the real deal.
I will be glad when sifr is dead--hopefully it will be next year.
