The answer to the question about how often one should blog really is “it depends.” It stands to reason that a blog that hasn’t been updated in a while will not attract visitors and certainly not repeat visitors. A blog that has already built a community will consist of members who have certain expectations regarding frequency. In my case, I learn something new most everyday given my range of interests, though a daily post may not be realistic given other demands on my time.
In hindsight, I suspect my earlier attempts at blogging weren’t sustainable because I had ambitious expectations of depth, breadth, and frequency of coverage, to the point I simply couldn’t physically or mentally manage by myself. This time I plan to approach it differently by micro blogging at least once a week and writing more in depth once or twice a month. The focus will depend on what’s happening in each area of interest with notable advancements and my problem-solving needs driving that focus.
