It depends on what you want to achieve. If it's posting activity i'd probably do as you say. Unless you want to regularly drop threads or ideas for people to get involved in. For the news that usually means either direct reporting in doms or invasions, doing an overview type of post, monthly news broadcast for example, as well as weekly small updates when they are warranted.
If it's to have a minor to develop over time, activity or not, then I'd keep it. You can have tech, locations, and minor lore references that people can browse to see what it's all about. In this form, to me, it's like an expanded directory for code or factory lore entries, as well as a place to index important information or threads you have done.
