The “point” of Twitter is communication. It’s active and viral.
For example, let’s suppose I find a cool website/blog post/article and tweet it. Then, several of my followers like the tweet and decide to re-tweet it to their followers. The dissemination can be exponential. Anybody can follow me and I choose who I want to follow. It’s like being at a cocktail party with the world and being able to participate in any of the innumerable conversations.
An original tweet:
If you use search.twitter.com/advanced you can find people who live nearby and who share your interests. The benefits of that should be obvious. I learn lots of things about my community by following local news stations, employment sites, and neighbors.
I also follow freelance web developers, business experts, marketing experts, social media experts, and media outlets. Oh, yeah, friends and family, too.
There are also tweetups for those of us who still enjoy eye-contact and facial expressions.
I recently enjoyed a 2 for 1 breakfast special at Sea Dog Brewing Co.. It was advertised only on Twitter. Woo hoo!
