It’s not quite as simple as pasting a link. Do you know what an RSS feed is? (It’s a machine and human-readable format). Most blogs have an RSS or ATOM (another flavour of the same thing) feed. Groups can use these feeds to get the headlines from an outside blog.
Seriously though, I just keep writing. Almost every day. Over time it gets easier to write to a high quality with a reasonable volume of posts. At least I hope so because I’m constantly behind on my self-imposed schedules.
