We are seeing the same thing at https://starthq.com. We've been getting a disproportionate amount of traffic from IE gallery as a result of being the most recently featured pinned site for the past 6 weeks in the US: http://www.iegallery.com/PinnedSites

There are a few other patterns we've spotted about IE users:

They're older - we can deduce this from the the fact that many include their year of birth in their email address.

They're less tech savvy, we see people typing in in all caps, using the search as it wasn't intended - and we've actually had a few get in touch via the feedback form asking for tech support.

Also the conversion rate from visitor to sign up user is consistently 3x that of Chrome.
