Mighty introverts, we can think and analyze very well, but sometimes we don't show that same brilliance to the world to our best advantage when we're face-to-face with other people. Shy people (who may or may not be introverted) may feel the same way. Sometimes it's easier to put our ideas down on paper or the computer screen so that we can plan them out and express them properly.
Web 2.0 and other Internet technologies have given us great communication tools that will allow us to communicate as well as anyone.
Here are the five easy ways for an introvert to communicate:
1) E-mail: you can compose E-Mails on your own time and craft the message that feels write to you. You can take as long as you want to get it right the first time. Just make sure that you are using an effective E-Mail writing strategy. If you are looking for ideas, you might want to try this article about writing effective E-Mails. Don't worry about the heavy emphasis on business E-Mails, this guidelines will apply in many scenarios.
2) Instant messaging: short, quick bursts of thought in real-time that can still be meaningful. Emoticons can help you deal with your feelings in a humorous and positive way. Believe it or not, if you get your audience's (nearly) undivided attention, you can have a good conversation without having to worry about body language, tone, or word selection. You can just send and receive the message without the physical filters. There are many IM clients out there, including AOL, (Microsoft) Live, Yahoo, and Google.
3) Twitter - you can broadcast to the world similar to the way that IM works, but you can reach a massive audience. Twitter is part of the microblogging phenomenon. You can also direct "Tweets" to individuals and/or send private messages. Beware the 140 character limit, however! You might want to couple this one with instant messaging or E-Mail for better effect. Caroline Middlebrook has written an excellent Twitter guide.
4) Blog - you can set up a swell blog like this one! ;)
5) Blog comments - blog comments can provide an excellent way to both make intelligent, thoughtful commentary while getting yourself noticed. Again, Caroline Middlebrook and ProBlogger have both written excellent stuff about blog comments. Note: search their blogs because they have multiple posts on blog commenting.
