Tumblr, which is basically halfway between a blogging platform and Twitter, allows users to post photos, videos, and text. Critically, it also allows users to “follow” each other and “re-blog” the posts of others.
The latter concepts, which Twitter has also capitalized on with amazing success (through “following” and “re-tweets”), inserts reblogged posts into each user’s timeline stream. Thus, anyone who “follows” a user, also sees the re-blogged posts.
This turns Tumblr users into editors and curators in addition to content creators.
Tumblr an amazing free tool (blog or website replacement) that lets others spread the word about your art. The barriers to posting content — written word, photo, video, repost of someone else’s post— are incredibly low. No other blogging platform is as easily syndicatable and spreadable as tumblr.
