Pardon the dust...
After some consideration, I've decided to move from Posterous to Tumblr.
Since Twitter's purchase of Posterous months ago, the microblogging platform has endured, but for how long is anyone's guess.
I realize this has created broken links to walkthroughs and project descriptions, but I felt the change should come sooner rather than later.
Eventually, searching for walkthroughs and tutorials such as fusion tables & highcharts will lead to the proper page. Until then, apologies…
The experiment was short lived. Tumblr's search left a lot to be desired, so I'm back to using Posterous as the main platform.
