There are three types of blogging:
- Fast – Twitter
- Medium – Tumblr/Medium
- Slow – WordPress
Twitter is a micro-blog because you write in a succinct 140 characters or less to get your message across. Naturally, Twitter is for breaking news and conversation.
Tumblr is a bit slower then Twitter. The feed is lighter and the posts are lengthier, capable of mixing all media types: Images, videos, GIFs. Tumblr is a social network on top of a blog, but it's more about showing inspiration rather than snarky conversation.
WordPress is a more traditional form of blogging. It allows for stories and thicker analysis. The platform is customizable but the content feels more rigid, like a news site.
As a blogger, I prefer to first write for the medium paced thinkers. Tumblr allows me to post a juicer piece like this without rambling on too much as well as a quote or photo to express myself, kind of like a pin board.
But it really doesn't matter which format you choose. Just share what you think is interesting. Teach the world something new. Show people that you have the ability to think or synthesize other people's thoughts. Think and create out loud. Just avoid using your blog to complain.
