Does Twitter make sense as a marketing tool? I think so. Twitter is an ideal tool for savvy marketers for a number of reasons:

Immediate contact.
Unlike email, which is typically tied to a desktop or notebook computer, text messages are much more direct and immediately accessible via mobile phones. Even those of us who receive our email on our mobile phones are much more likely to receive text message notification before checking our mobile email accounts. Somebody sends you a text, you receive notification of a text, you read the text. This happens millions of times to millions of people every day. Text messages get read more often than not.

Brevity.
Because most text messages are limited to 140 characters, you can't get long-winded. Messages are short and to-the-point. An update about a new blog post or a quick recommended link are all you have space to write about. Brevity also enhances delivery and reading because we know text messages don't take up much of our time.

Frequency.
This is both an advantage and disadvantage of text message social marketing. Text messages are collected together by conversation strings if at all. There aren't many good ways to view all of the messages you sent or received by going to one convenient location. There are some RSS feed tools that can be used but most messages aren't tagged or categorized for easy retrieval or reference so you see them all no matter how unrelated. Depending on how often you receive text messages, you may miss some of the earlier messages or decide that you don't want too receive every message immediately.
