It's poor programming of the site. There are vast number of people on mobile devices who won't be able to use these features.
To be fair, we are talking about the main site. They do have an easily accessible mobile version. Just that on my only current mobile device, (Nokia N900), full-version websites are fine, Maemo version of Firefox is included, so I haven't had to bother with mobile versions of anything.
The N900 has the same problem, and I don't see it as the site designers' fault. It is simply that the device OS has no mechanism for the normal click-and-hold then drag on a touch-screen. I blame the technology, not the site. It only needs a key or key combination to lock the screen and allow drag, from the user perspective, and after that most of the code is already there.
I can tolerate it on the N900, but on a decent-sized wham-bam-"I'mTheGreatest" piece of kit I'm disappointed.
Surely it isn't beyond the wit of the programmers to cater for this sort of thing? How do you manage in the WP app? Even on these forums I use drag/drop a lot.
