It's just occurred to me that since I developed my 'new look' blog-style portfolio site instead of my old static one, I haven't included any of the past pieces I did for The Independent's Business Monthly section, which was focused on SMEs.
There was an interesting feature I wrote on the unscrupulous practice of 'passing off' called Internet Domain names: Don't get caught in a rival's web. Unfortunately, I had a great case study for this piece and they pulled out at the last minute for fear of legal action against them, so the feature ended up being mostly advice-based.
