I've noticed this behaviour a few times the past weeks in the weekly newsletter. A person comments or posts an answer on an old question that was once popular and it becomes one of the two greatest hits from previous weeks in the newsletter.
Doesn't from previous weeks imply that the question shouldn't be older than a few weeks? The name sounds a bit odd to me when it's about a question that's more than a year old.
Example from this week's newsletter: Android requires compiler compliance level 5.0 or 6.0. Found '1.7' instead. Please use Android Tools > Fix Project Properties.
Is this meant to be behave like this or is this a bug in the newsletter generator?
