We have a proposed layout for a linkblog homepage at links.daveverse.org. It's a work in progress, and it's not yet available at the GitHub repo. The layout is very inspired by the links tab at Scripting News.
Right now the linkblog homepage is an option in the Baseline theme. When turned on, it activates a linkblog template for the homepage. Is this the right way to do it? Should a linkblog layout be a separate theme or a child theme of Baseline? I don't know yet. 😃
For the layout I* am making a lot of assumptions about linkblogs.
*I say "I" here as these assumptions are completely arbitrary and were not made in consultation with anyone else. They can certainly be discussed in the GitHub repo.
