Great suggestion, you can use the article API already to do this (providing the URL of the post and the 'tag' parameter), but maybe you are thinking of analyzing other types of content? Or perhaps the ability to POST your own text data instead of just the URL?
Exactly. For instance, if a user is typing in a blog post, right now the flow would be:
1) User submits post
2) I create a page for their post
3) I call your API to analyze the page
4) I update the page with the auto-tags
5) I redirect the user to the post
This is kind of slow. I could do it with AJAX calls too, but it's still an awkward flow. A better flow would be:
1) User submits post.
2) I pass the text of the post to your service.
3) You analyze the text and send me back the tags.
4) I add the tags into the post and create the URL.
5) I redirect the user to the URL.
This is a much more natural flow.
There are other solutions in this space, like Zemanta, but they generally suck. If I enter a term like "social network" into Zemanta it will tell me Google Buzz is a tag... which is ridiculous.
