I would suggest that tagging these articles would add a great deal of value. The chronological list is good, but adding tags or categories of some sort would make it easier to navigate.
I've thought about this a lot, but I'm not entirely sure how to tag it in such a way as to be useful... do you have any suggestions as to the types of tags you'd like to see?
Possibly part of the problem was that I was looking at it from a "general startup" point of view (the narrowing down to early founders is recent). Perhaps with a narrower focus, tags will make sense.
I'm not entirely sure if this is possible, but how about categorizing the articles based on different stages or phases, which a startup founder has to go through, from start to going public with the startup and making it go huge. Something like that?
Indeed better than tagging. Those who know the 'stuff' might not agree but the 'step by step' is always better for novices (read me). And not to mention, 'step by step' will be a useful keyword for SEO.
