I just read your post. That's an interesting idea, however to make it work both the writer and the reader should have the plugin and that's quite hard. Moreover, it require a new step for the writer...
Another way this could be done is by adding a filter on the reader side based on the posts' tags.
But then, I would do it more in a blocking way,like "don't show me posts with tag XXX". That way, once you see a post you are not interested in, you could click on an "hide" button, that asks you which of the five tags of the post you would like to hide from now on.
After that all the posts with that tag will be hidden.
What do you think?
Hey there. Thanks for giving it a look.
I immediately understood that there would be some things that couldn't feasibly be implemented in an extension.
At the moment you are working on a 'top-five tags' option. You are now talking about what sounds like a 'block some tags' option - and that sounds like a logical continuation upon that which you've been working on. In that event there would be no need to have it active on a per-user basis (and would be a lot lighter in overheads also).
Sounds like a plan. ^_^
