Affiliate Marketing Secrets

I’d like to start a blog, not to make money, but to organise my writing and to make it accessible to a larger audience. I am aware that I need to narrow down my blog topic so as to be able to market it effectively. I would like to write about current affairs and prominent issues in politics, law and technology. Is this too broad a niche?
I’m thinking the following sorts of posts:
– Opinion pieces
– xyz subject explained: e.g. something in the news put into context and explained simply
– Personal life columns: light-hearted, off-topic posts about things I encounter in my life
– Tech how-tos/guides

How can i set best high paying companies ads on my adsense ads running site? My site is on technology niche. i am reviving 0.15$ CPC. i think its too low. Can i set high companies ads for my website ?

It seems like there is so much technology out there (Cisco, Juniper, XTML, Pearl, Adobe and so on) there is no way one person can grasp all its concepts. So I guess my question is, whats the best way to base my career path in IT? Is it to study a niche, like Networking or Programming? Or should I spend my time learning about bits and pieces of as much as I can to be more well rounded?

Now a good paycheque is very important to me. I have a Bachelors In Electrical engineering. I love technology and i’m also good at managing people.
I know about the wide network an Mba allows you to develop and the never ending opportunities in a variety of sectors for an Mba graduate. Should i choose this over the niche field of electronics where opportunities are few but the pay cheque would be on par with an Mba grad?
I have loved electronics and has been a childhood dream to work in a lab where world changing work goes on.
I sd keep in mind even the tuition fee for both. An Mba in IIM wd cost me around 13lac while in IIT/IISC id be paying peanuts.
I want to write either GATE or CAT and have given myself till end of nov to decide which. I don’t mind the hard work needed to be put for either.
Any and all kind of advice is welcome and highly valued! Thanks!
(I’m working now in the software field if thats anything)
– sorry for the category or if u see this qn ppping up everywhere. I want to get as many ppl as possible to answer this.

Hello, I run a technology niche blog which received around 1000 hits a day. The blog was started on 17th May 2011, i.e its 56 days old. Is my blog doing fine, good, bad ? I know this is a lame question. But just need to study some statistics. Here is my blog link:
