The first thing you can do in promoting any business is to drop the 'webonese' from your posts. Although it's fine for personal emails, abbreviations like 'ppl' do not make you stand out as a savvy business person.
In particular, promoting your article site, you have two venues of promotion.
If you are looking for more articles for your site, you must promote to the writers and show them why submitting articles to your site is more beneficial to them than submitting their articles to other sites.
If you are looking for readers, or webmasters to access your articles, you must show them why it is to their benefit to come to your site first rather than other article sites.
