The new blog I also think has a much more attractive theme and more clean and professional look-and-feel. I also am planning to put a lot more effort into each individual post. I will probably update much less, but I anticipate the posts will be much higher-quality.
I also chose a witty name (and more descriptive too), finally, instead of sticking with the rather dry name of my old blog. The old blog will still remain up.
I hope you find this blog an interesting read!
