I can't see why anyone would want to stop me to be honest.My Tumblr, nicharry, has revived my ability to post content online without too much thought, reactively and instinctively in a short space of time.I am besotted with Tumblr.Let me explain what the service is, in my opinion, for me. It's a lifestream sort of a blogging platform. A stream of consciousness I think sums it up relatively well.Tumblr has legs in the market right now for one simple reason. It's simple to use. I have a "Share on tumblr" widget added to my browser. I click it and automatically a popup appears and allows me to share video, audio, photo, links, quotes and other types of media. The little widget handles the linkback to the source and posts to your Tumblr immediately.I've also installed the Tumblr desktop app for Mac OSX which allows me to tumbl from my desktop. Simple, easy and effective.Furthermore the type of content that I've come across on Tumblr is incredible. It's alternative, different, cutting edge, pushes all the boundaries and seems to not abide by the regular rules and regulations of producing content. It's a place where anyone and everyone can find a home.It subscribes to a very similar model to that of Twitter. You can follow people's Tumbles and they, in turn, follow yours. You can see everyone who you follow in your Dashboard and follow their content as it is published.The person who got me on to Tumblr is Wes over at BlackNotes. If you have some time, head over there and read Wes's Tumblr, you'll be occupied for hours.But for the moment head over to Tumblr, register, choose a theme and tumbl-on.
