Robert has a good simple tip on how to make your posts easier to pass around for your readers and suggests you write in a granular style. To put it most simply.
‘Make one post contain one idea, or set of links.’
I agree with Robert although can think of times when you might want to include a few grains or ideas in one post. Some bloggers build their whole style around having multiple ideas in one post – however I personally generally find these blogs difficult to link up to and read. I’d much rather see one post, on one topic, with one heading that describes that post.
This is especially important for your readers who use RSS to read your blog and who either just look at your titles or who select to only see excerpts (the first few lines) of your post.
I would also add that it helps with the search engine optimization of your post if the search engine’s bot only finds one topic in each post rather than numerous.
