I have added a section in the right column for my Presentations. Have given links to the blog posts which link to the four presentations I have made in the past 6 months.
Much of the thinking for my presentations happens in this blog and the Tech Talk columns. What a presentation does is nicely summarise for others what one is thinking. A limitation is that the presentation is at best an outline. It does not present the complete thinking the way elaborate writing (or talking) does. But still, they give a quick flavour of what I am thinking.
