Tagging Your Blog Posts - Useful?

[SWKurt]

Has anyone demonstrated measurable value from routinely tagging your posts? I am of the mindset that what is good for a user/reader is good for SEO and therefore the posts should be tagged. I wanted to see if anyone else had specific experience to the positive or negative.

Please someone help me and tell me if Im wrong - some time ago some (maybe even now), some websites like technorati or other kind of... were (are?) using tags to categorize posts, so if you wanted to appear under some categories with your freshly added posts, you should have them tagged -> but I tell you, I checked that long time ago, I might be wrong that's why it would be great if someone would add something to this...

and if it's the way I mention... was it (is it?) technorati or other sites?

However, I like to tag posts as it may be useful for you. You never know if in the future you will want to add section, page or something else on your blog... and tags might help you to easier accomplish it...

I still do not need it, so I can't give you any working example... but in my opinion it's good to tag posts. I do that "just in case", as maybe in the future I will need them, or any of plugins will want to use them... and if I have 200-500 posts I will not be happy to go back and add tags to each of them - and im sure there are some good plugins that need post tagging.

If users find it useful? Depends... each user is different... however good tags are always helpful and gives something extra... however, sometimes may add "mess"... (I know my answer is a bit messy, but I hope it gives you some answers.. ideas).
