I read the original post in my reader the other day and I must say, I agree with them!
Why bother writing such a freaking awesome post if you’re not going to make it easier for others, especially the general public who haven’t found you yet, by tagging it!?
For Example: My Updates posts I usually categorize them under SVM and TB and updates then put each separate author’s name as a tag! This makes it easier for readers to find the other authors, for me if I should be looking for stuff written about a particular author and for other readers who forgot to follow or favorite an author. They can type in the name or fandom and come to my site where they might be able to find what they’re looking for.
It’s really easy once you get the hang of it 🙂
