Comment spam hurts your blog.

Block and manage it by

• moderating comments, or requiring commenters to solve a captcha (no need to do both)
• marking spam, which trains Blogger's spam filter.

NOT feeds: exclude

In brief

• Use the NOT operator - (minus sign) in the feed url to exclude a search term.
• For multiple search terms, use AND NOT (+-).
• Follow the feed in a reader or use it to create a dynamic list in your blog.

A feed that combines two things

In brief

• Use the OR operator | (or "%7C") in the feed url to filter the union of two search terms.
• Follow the feed in a reader or use it to create a dynamic list.

A feed of overlaps

In brief

• Use the AND operator + in the feed url to filter the intersection of two search terms.

Tailored blog feeds

The insight that your blog is a database unlocks special blog pages tailored to combine subtopics.

Not just a page showing all the posts you've labeled "bread" (an old trick, and a handy one), but a page combining posts with two labels ("bread" plus "cheese").

Or, a page restricted to posts bearing both labels ("bread" and "cheese"). Or one that excludes (all "bread," except if also "cheese").

Well, you can do the same things with your blog feed.
