Try new things, all the time. Especially those that are a little outside your comfort zone. This is the Internet — don’t act like you’re writing for Time Magazine in the 80s. Stories can be pictures, charts, lengthy essays, numbered lists, or 140 characters.
Dan Frommer, blogging about better blogging.
So many blogs confine themselves to simple prose and ignore the opportunity to integrate media of all kinds. Support for mixed media is one of the reasons I love Tumblr and have stuck with it for so long. Some people have one “real” blog where they put their long-form text, and a separate Tumblr blog where they put everything else. I don’t think there’s any reason to keep that distinction. Indeed, I bet that in most cases, merging the two would yield a result stronger than the sum of its parts.
