This may not be an appropriate place for this suggestion, but it might be. Related to a previous comment I made and the mention of the job ads debate and the sidebar idea.

I would like to see various concrete projects that should be referenced often, like the akrasia tactics review or links to various power tool projects on the main site. If there were a sidebar which contained something like a list of job ads relevant to the topics of the site, a link to akrasia tactics to help get everyone focused, and links to various power tools to help people pursue their goals effectively or find projects to contribute to.

These seem like topics that are very likely to be instrumentally useful to most users, and far less likely to be used or known of when they are not on the front page.
