While Tumblr is a blog platform, it is much more “conversational” than other blogs. It’s more like Twitter in many ways – following blogs, re-blogging, searching hashtags to follow topics and favoriting posts to name a few. Now they’ve added a mention feature that will notify a user when you include them by using @username in your post.
Tumblr offers some additional features – like the ability to schedule when a post is published or to create a queue which spaces out your publishing at intervals you designate. And there’s no 140 character limit either. With the Tumblr app on your phone, it’s easy to post photo updates any time too.
