There are only 2 problem solving Technology blogs I consider to be the best in Nigeria from my experience.

These 2 blogs will not hesistated to feed u back with suitable and quick response when u ask them questions pertaining to their niche, even if they don't seems to know it.

These 2 blogs are:

-OgbongeBlog.com

-Yomiprof.com

Although, Yomiprof doesnt publicize his direct phone number as Jide does, but u can still make use of yomi contact e-mail form, even if your question is urgent. I can assure u he will reply within minutes.
