Further, you could actually put forth why you disagree with him instead of taking his comment and applying an out-of-context switch with the subject. Comments and articles are completely different from a business on scale and intent (seriously, months to think about a comment? However I do re-read my comments to make sure they are sound, so maybe minutes). What I think you meant to say is that writing and sharing thoughts is okay no matter what stage you are at; in that I agree, but I disagree with writing about weak conclusions (weak because 14 days isn't enough time to gather the data and experience necessary to clearly conclude) based on the fact that as an author on the internet, drawing conclusions too soon can actually hurt your business.
Even if the author had made a "conclusion", he is welcome to. If he learned something in two weeks, congratulations to him. If after two weeks post launch, and months of development, he cannot plausibly have "made a conclusion", then no one on this thread has the right to "make a conclusion" after reading one blog post.
