Hopefully they've also gotten better people triaging the bugs than in the past.

Too many times I've opened one-liner JS bugs with references to the specification that get closed because they need a public website to repro. I've even had bugs which link to the failing W3C spec test get closed as 'not repro'.

I used to work at MS and was often thanked for the quality of the bugs I opened (frequently IE bugs!). They must have different people triaging the publicly submitted bugs because I'm pretty sure they don't know how to even open the dev tools.
