I have been considering the idea of having a blog and my own website for a very long time. It must be a good time back: Yahoo! just acquired GeoCities at that time. Other options came later but it never happened.
I just won’t make it about myself. I always thought it could be a good idea to have a private space for general sharing of ideas and miscellaneous topics of my interest. Eventually interacting with people and learning from these experiences, etc. Good news is that a blog is not needed for this.
In fact I have been encouraged and supported for my good friends and colleagues to do it.
