When you decide to "get back into blogging" you have a lot of decisions.
1. Should you get back into it at all?
2. If you do, will you post once, maybe six times and quickly retire once again?
3. If it's been awhile, should you start a "new" blog with a new name?
4. Should you focus your topics, or just share random pondering?
For me, it goes back to purpose, and the purpose of this blog has always been aimed at myself. A place to write, because writing helps you think. Then a place to catalog one's "findings" be it web pages, neat things, articles, etc. As such, there's really no reason to start a new blog.
So:
1. Yes
2. So what
3. No
4. TBD
