I have been thinking if this is the right decision. A blog should be a two-way communication. But come to think about it, it may not be as efficient to have a comment box actually. Why?
Comments take effort from the commentator. The commentator has to come to your blog, read your article, and put in a comment. How many people are actually writing blog comments so regularly? It may happen for once, for twice. But to write a couple of comments regularly, this person must be a big fan of those blogs. If not, is there any other objective for doing so?
On the other hand, it also takes some effort from a blogger like myself to check if the comments are actually spams. And when the comments start coming in, I might have to deal with the debates too. I would rather put my focus on building up the contents in this website.
Reading through my past 2688 comments since 2007, I decided to delete them all and start all over again. The reason is also because I have received feedback from some commentators requesting their comments to be removed. I guess they must have thought that it is bad for search engine optimization to post too many comments pointing to their website. Having a deletion of all the comments is also a way for me to reset my blog as I am trying to clean up. As for now, the comments will still be allowed till I find it not so relevant in future.
