I've been contacted by a blog reader that our way to use 'categories'/'tags' which show up in the right column is not very helpful. They are supposed to be used to navigate to certain entries and should not be used to define the author names. I agree with this assessment and propose that we define some conventions and then change the existing entries.
I still think that we need to use the author name as one of the categories since there are many different authors in this blog. I suggest however that we only use the last name.
Additionally I think it makes sense to use one of the following categories to define about which product the entry is about:
Furthermore I think we should only use a well defined set of other categories:
Let me know what you think. If we can agree on this set I offer to do the changes to all existing entries.
