I love writing. If I had to choose between breathing and writing I would choose writing hah. The problem is that this is putting a massive strain on my other time commitments. If I did not have to work and was making a full-time income online I could write hundreds of articles a month. But the fact that about 50 articles is still not generating as much income as I want is causing me to cut back on blogging. If you are a good writer one 500 word article per day should not take you longer than an hour to write. It's easier with practice.
If you are updating often then you should have a blog. But you are saying that you will add only 1 or 2 articles per month. A website will be enough for that.
In my opinion - Blog for quick index by search engine and informal type of content. Website For the large content and look seen formal type of content. For me, I very prefer blog more than website. because it's very easy to use.
yeh i have found that with my site as well.... i posted my blogs to blog carnivals.... the google duplicate content filter then comes along and eliminates links after a while.... my advise is if you are going to use an article.. then make sure it is indexed on your site first i also have a post on article software that you can read here http://www.traffic2mypage.com/product-reviews/tools-to-help-increase-web-traffic-to-your-site-articulately/
