If you bookmark Dave's blog, you have to check his blog every day to see if there's something new, even if Dave only posts monthly. Or you check less often, and sometimes discover a new post long after the discussion in the comments has come and gone.

If you put Dave's blog in your RSS reader, one day "Dave (1)" shows up in your list of unread sources and you can read his new post immediately, and you didn't need to think about Dave's blog any other day.

I could use the "all articles" feed in my RSS reader (TT-RSS), but I would never do such a thing unless all the blogs I follow had similar posting frequencies that would mesh well together, which they don't. I never use the front page of Reddit for the same reason: the busy subs would drown out the ones that get a post a week.
