Blogging is really for two main reasons, order depends on your priorities.
1. For yourself, to help clear your mind and clarify your thoughts.
2. For convincing your future employers you’re not a con artist.
I thank bloggers for all the times I've had tech problems that I wouldn't have solved had it not been for them writing up their experiences.
And on the other hand, as a consumer of such information, I find it harder and harder to find original indie blogs. I'm still looking for a good blog search engine that allows me to find blogs on Niche topics. does anyone else have this problem? or is it just me? the best i can usually find is something on quora.
