General Or Thematic Blogs?

Which is better to monetize, a general or thematic blog? I have mixed feelings about it. With a general blog, you can attract more visitors of various interests. But if you were using the blog to get visitors to your website selling certain products, you would get more targeted visitors with a thematic blog. What do you think?

Yahoo.co.uk And Yahoo.com

I just created an email account on Yahoo. Actually I want it be myaccount@yahoo.com, but somehow I have made an account named myaccount@yahoo.co.uk. Do you think the extension matters? If someone sent an email to myaccount@yahoo.com, would the email reach my inbox (myaccount@yahoo.co.uk).

Any Regulation?

I notice that recently many new payment processors promising better services and less fees were launched. That's good as we will have many options of making online transactions. But how secure are them? Is there any regulation on starting and running an online payment processor?

Visa Or Master?

I have a Visa credit card and use it to make (especially) online payments and get my PayPal account verified. I never got issues with it. Anyway, the bank I use grants a Master credit card with no annual fee applies. Actually it's mine no matter I activate it or not. What do you think? Should I stop using Visa and move to Master card?

When To Give Up?

When running an online business, we are advised to try and try again till we gain profit, earning or whatever our goals in starting the business, instead of giving up after failing in the first try. But, how to judge when to stop? How to know that the business is not worth the time and money invested anymore?
