I don't suppose you are wrong in general sense but each one is writing the topics he/she is comfortable about and those are my topics

I have hard time writing about stuff that I like, I would think its impossible to write about stuff I don't care about.

Still my topics are more on web development and not SEO so there is some more room of writing fresh content, and if you have noticed I am not making any announcements about such and such product release or such and such service.
I don't enjoy those posts.
The stuff I write about either I developed or found usefull (otherwise I don't find any value in posting them) so it is unique no matter what you say.
If I find/develop/discover something and do a search and realize that someone else has written about it I lose interest to write about it. That is the reason I only have 9 or so posts in 3 months.

(Heck, Its been almost 3 months in V7 and I have not posted more than 50 posts because that is my nature to post something of value or a genuine question or anwser or nothing at all)
