Hey, we just implemented the Windows 8.1 "live tiles" feature for the main MetaFilter site, but since I don't know anyone with Win8.1, I can't really test it. If someone with Win8.1 could test it, screenshot it, and let us know if it works? [more inside]
I changed the way new/same window targetting is done, so if you have your preferences set to "open links in a new window" and links internal to metafilter are spawning new windows, let me know and I'll fix them. Only links within posts, comments and on the front page should lead to new windows, everything else should stay the same.
