Every once in awhile, some one gives such a kick-ass answer full of so much information that I just bookmark it. I have a small collection of answers that I thought were really insightful, that I wish I could nominate for "answer of the month" so that new people that come to the site would be able to click on "all-time awesome answers" and read some of the content that was exceptional - even if it was done a year ago. Like a hall of fame of best answers. We could automatically pick these based on "most votes this month" or something similar.
The "question" Most Viewed Questions on GIS.SE demonstrates one mechanism that might accomplish this: you can query the SE database itself to find what you consider to be "best" answers.
This is exactly the sort of thing that the Blog is ideal for.
