Comments policy

Currently, there has been very little difficulty with abusive comments on this blog. Therefore, the comments policy is left relatively unrestrictive. This is a "do-follow" blog, and bloggers are encouraged to leave a link with their quality comment. This blog takes a "do-not-feed-the-trolls" approach to abusive comments; they will not be deleted unless they become disruptive. Comments judged to be spam, in my sole personal discretion, will be deleted. This policy is subject to change without notice at any time.
