There seems to be ambiguity and contradictions regarding whether or not guest blogging is beneficial. However, I hope that someone will still want to write a post which I will use as my 400th post (which I expect to be published by the end of May). I asked a fellow blogger to write a post for my 300th post, and I then decided that I should do this for my centenary posts.
As I see it, there are a few topics for such a post at my blog:
1) An Expat's Guide to [your city] modeled after my recent An Expat's Guide to Singapore. However, if you live in Mumbai, Hyderabad or Kolkata then please do not do this.
2) A Resident's Guide to [your city] in which you describe your city. I envision that this ought to be modeled after WikiTravel, but more in-depth.
3) Any other topic that you feel passionate about. However, it would be nice if it could fit nicely in my "labels" or categories (located at the top of the auto-hide tab at my blog.
As a blogger, I am too poor to offer anything in terms of payment (although I still have an unused Airbnb voucher, which does expire soon). Of course, you are free to promote your own blog, website, or favourite cause.
