Timezones! (I assume.) I diligently posted at least once each day for #mbaug photo challenge, and used that tag so I could easily collect the posts. MarsEdit shows 1 post (or more) per day. A Micro.Blog Search though shows something else — ‘incorrect’ dates. Timezones?

Screenshot of MarsEdit post search. Micro.Blog Search result page with clusters of posts rather than consecutive days. Timezone info on the layout/posts/single template page.
