I'm not sure I can phrase this other than as "why is my most popular question so popular?" but I am genuinely curious as to how I can get first the Popular Question badge and then, within an hour, the Notable Question badge for my question LaTeX3 versus pure Lua. I remember checking after getting the first one; it had about 1045 views. Now it has more than 2600 (which is in turn about 50 more than it has a few minutes ago when I got the badge). Did it get linked somewhere? Granted that it's a popular question; it's been relatively stable for most of the last week.
The question was posted to Hackernews, which can easily drive that kind of traffic if you make it to the frontpage.
