The adoption of PHP ... 6?
As I wrote before the adoption of PHP5, so long after it has been released is still quite low, I was surprised by David's HOWTO on installing PHP6. I know, this one is aimed at those more tech-savvy people who want to fiddle around, but I truely feel that the PHP Group should focus first on promotion PHP5 more. I don't think a lot of people will adopt PHP6 while they're still working on PHP4.
