Sure, it's just kind of weird to comment on an article about a web app when you don't use web apps. I don't own an iPhone but I wouldn't comment on an iPhone app and say how much I dislike it for being an iPhone app...
I do use RSS clients, however. Serverless RSS clients, even.
I think it's perfectly legitimate to for me to comment on why this particular serverless RSS client does not fit my needs and what I believe better alternatives are and why.
Anyone with similar needs or who may not have considered or been aware of the alternatives might benefit from my comments, and someone who has experience with other software that might better suit my needs might mention in return, which would be of benefit to me and others with similar needs or concerns.
