Tuesday night, I decided to commit my digital diary to Tumblr. I had been considering the move for months, but let my personal blogging languish rather than switch or stay with TypePad. My problems with the Movable Type service:

• My work blogging for Apple Watch and Microsoft Watch has become all-blog-time consuming. I need to be able to blog shorter posts and more varied content, faster.
• TypePad—and even WordPress—feels oh-so last century. The interface is too busy and complex and features favor text-heavy, cluttered blogsites. I want something cleaner and simpler and that encourages mixed-media content. I write for a living. Spare time should be about creative blogging—audio, photos and video.
• A single blog can no longer be container for my entire digital persona. My online presence is multi-service—and often I wish it wasn’t.

By comparison, Tumblr is an amazingly efficient and noncomplex blogging platform. The tumbleblog concept resonates well with my lifestyle, and Tumblr delightfully delivers it. Emphasis is shorter posts and mixed media. What’s not to like? But I had Tumblr concerns, too:

• There’s no obvious import mechanism, which means I wouldn’t be easily bringing past blog posts to the new platform.
• I couldn’t discern a business model. David Karp has got a great blogging platform, but is it a sustainable business? I’d feel more comfortable if there was a paid version.
• No business model means Tumblr could suddenly close up shop, which is a concern given the current recession. Web startups are laying off or closing up. Will there be a Tumblr in six months—heck in three?

What the hell? I like the platform, the ability to follow other bloggers on the system and Tumblr resonates more with my digital lifestyle than TypePad or WordPress. If Tumblr ever closes, yeah, this record of my online life goes poof. That’s OK. I believe change is constant and should be embraced rather than avoided. So here I am, tumbleblogging.
