No...I am no the best proofreader.
Yes...I do actually proofread my posts.
No...I usually never find all of the mistakes.
My wife kindly reminded me, recently, of my many, many grammatical errors. I was sure they happened, but most my feedback had nothing to do with the technical nature of blogging. Unlike most, I do not mind input that helps me improve me writing...especially that of my loving wife...after all, she is the reason I started blogging.
I do love blogging. It not only suites a great purpose of informing friends and family throughout our crisis and life, but it give me a record of things, a much needed place to vent creatively, and may even be something I would love to do for a living some day.
