A site I maintain tweets every time a blog post is published.
Since the editors of the site have gone a bit mad with the ability to change the apparent date a blog post was published (back-dating as a layout tool), the twitter stream is the easiest way I have of knowing the actual date of publication.
I now need to make a case for the efficacy of blogging (in conversion terms) and have turned to Google Analytics, who have been hoovering up our visitor data for over a year. My first thoughts were therefore to add annotations for each blog publish event, so that the ramps and spikes are more easily interpreted.
Is there any way of importing data to be used as annotations? How hard would it be to massage the twitter stream data into a format that Google might play nicely with? Would it just be easier to manually add an annotation for each tweet?
