Twitter offers a more automated means of lead capture. With a target web site, either your own or the ‘offer’ money site, you are in a position to write short articles or blogs and then post Tweets carrying links to these articles. Keep those down to about 10% of the total, linking the other 90% to interesting on-topic snippets elsewhere on the web. Then use a good scheduler to queue a week or two’s Tweets and then let it run on auto pilot.
The main reason why leading world companies create accounts in social networks is to attract traffic to landing pages and websites. YouTube's video hosting by the number of search queries is second only to the Google search engine, and you can attract some of this huge traffic flow to your site / landing page by simply posting your video (and related links to your web resources) on this hosting.
The reason I started Apache Leads way back in 2003 was that I was a Diamond level distributor for a San Diego based MLM company and had quite a large business. None of my associates had any access to leads, so that's how we got started. The demand for leads grew so fast that I had to focus on getting quality, affordable leads in ever increasing numbers.
