I reorganized the categories a bit. I removed the Meta category that I never liked, and moved its content under Personal/Administration. The old permanent links to those entries don't work any more, but I don't know why anyone would have linked to them anyway.
Also, I recently renamed Entertainment category to Media, but now I reverted it back to Entertainment. I initially felt that some of the entries are not that entertaining but more like educational or for general interest. However, after looking at the title Media for a while I began to feel it's too plain and the word Entertainment has more associated value. Besides, there is a slim chance that someone has a link to an entry under Entertainment, so better keep it unchanged. But I might move some individual entries elsewhere or make changes to some subcategories, so links to those might get broken. Just need to live with that, I won't bother fixing it.
