I hope this is a joke. Instagram is pretty dumb....They could be working on a million other better apps
I doubt that very many people here actually care about Instagram.
I couldn't give even the slightest of fucks about Instagram myself, to put it bluntly.
The big news about apps like Instagram and iPlayer coming to WP is that it means it's seen as a serious, viable platform. Which in turn means that it attracts more developers which will attract more people to the platform.
Windows Phones needs to check as many of the "big" apps off the list and those 2 are a very good start.
edit: and it would be lovely for the sole reason of people finally shutting up about Instagram not being there and that somehow being a not so minor disaster.
