Posterous is still the 'Dead Simple'-est way to micro-blog on the Web.
You can look around and check it out. I was surprised that after all this time since it's inception that it STILL IS the easiest way to micro blog AND get that micro-blogging Word Out to your readers through it's social media 'cross-posting' feature which was pioneered by those same folks, Garry Tan and Sachin Agarwal.
It sure is a great service and I certainly hope to see it survive. It has been subsumed by Twitter, but I hope that Twitter keeps it around as a new complimentary service to the Twitter family. I think it is a great tie-in service to what Twitter represents. I guess we shall see.
Many have said that the future looks grim as regards Twitter acquisitions, and yet Twitter has not acquired anything like Posterous in the past, so I am eager to see what happens. Sure, the writing is on the wall. You can see that when you look at Twitters' blog post about the acquisition and the fact that they address the user's fear of having to move their blog (and how they will make it as painless as possible) within the first several sentences. Posterous says much the same thing in their blog post.
Everyone looks happy and that's awesome! The Posterous folks deserve this buyout! They've been great to me over the past 4 years and I'm really appreciative that they introduced me to the world of the micro-blog. I hope that what they created has life and breath enough within Twitter's birdhouse, to live on.
