Performance
I originally did plan to write one article per week (or one per day?). So I should have finished after only 9 months. My real "performance" is one blog article every 2.2 week. Not too bad after all.My main problem is the lack of free time. I still have many ideas of blog articles but not enough free time and motivation to write them.
Evolution
When I started this work in April 2013 only 262 readers where present in my list. 19 months later there are 322 readers. That is 60 or 23% more readers.All the numbers are from the initial 262 readers. I don't think that the 60 new readers would have significantly change of the results.
