Rameus - it sounds like you have a good handle on Social Media Marketing in general...The goal is to attract attention to your business by connecting with those that share an interest, and drive traffic to your business/website. Twitter, with 554,750,000 active registered Twitter users (source:
Twitter Statistics | Statistic Brain), it is certainly a good resource to do it.
danvolker - I would be happy to help you figure out Twitter, but it would require a lot of typing to do it here. In a nutshell, to build a following, you need to make yourself known and participate on Twitter. In just two months, my DuckDiver Twitter account went from zero followers to 352 without spending a dime. You are welcome to contact me for a one-on-one consultation, or wait for one of my next blogs on building a following. As for your other issues with Twitter, times change whether we want it to or not. If you would rather not participate on Twitter and focus your efforts in other ways, go for it! Nobody said you have to do it all in order to be successful. This blog was focused on Twitter because I have had many people ask me about it lately, and it is my personal favorite...at the moment.
NetDoc - Using content from ScubaBoard is a very good example of sharing interesting content on Twitter. I share ScubaBoard content on a regular basis, but it is important to remember that you should share a variety of content with your followers. Don't use just one source.
Most of all, don't let it become one-sided and impersonal...Don't forget about the "social" in Social Media!
