Biggest impact I've found which is not directly discussed in the OP: A great package repository (e.g. CPAN) can outweigh quirks in language design (e.g. Perl spaghetti code).

That's awesome, although it'd be cooler if the information appeared on a separate screen rather than obscuring the text editor.
I find this rather scary; most 'programmers' under 20 I know 'learned' programming like this. I mean; most PHP programmers you'll encounter on the web only know how to combine snippets; they don't think for 1 minute, they just search everything they need, copy/paste, change a bit. And what is frightening that actually quite large sites are made like that. And this practice gaining popularity too.
