Many of the blogging platforms, TypePad, WordPress, Movable Type, take the position that their technology not only provides a blogging platform but also serves to provide website functionality. I believe that their technology is probably an easier way to create a website for something simple like a consultant or professional services firm. The big advantage over a typical website is that one easily combines a dialogue with potential customers and the required corporate or personal information.
A nice example of a blog that also serves as a professional services website is Sandra Bessamra's blog. I like the way she used a widget to segregate most of the French language posts from her main posts which are in English. Simple way to show two of the four languages she speaks. Also, nice use of other widgets including Sophisticated Finance. Always a good widget choice!! Besides the previous link, the Sophisticated Finance widget is available from the lower right column of this blog.
Note: 50 readers read my blog through my widget on Saturday. Have to watch this statistic more carefully.
Thanks Ms. Bessamra.
