Twitter writes that link length shouldn’t matter, but the zillions of URL shortening services out there show that, for now, it does.

But why?

There are two main reasons to shorten* a link:

  • There’s a technical limit, such as SMS message length or email line width.
  • You expect people to manually enter the URL.

Right now, with Twitter messages limited to 140 characters and links forced to share that space with the rest of the post, URL shorteners are critical. But they’re working on a plan to accept longer URLs, and specifically shorten them for SMS messages. The full link will be available on the Twitter website, desktop clients, and other platforms that don’t have that hard and fast limit.

That will cut down on the demand for shorteners, but they’ll still be useful.

For one thing, there are other microblogging platforms out there like StatusNet.

For another, there’s email.

IIRC, the first URL shorteners launched because email programs often break up really long lines, including really long URLs. In plain-text messages, that leaves links not just unclickable, but inconvenient even to copy and paste, because you have to copy each line separately and paste them together. This will continue to be an issue as long as people continue to put visible URLs in email.

And then there’s the human factor. It might not be easy to remember http://is.gd/cGE8V, but it certainly takes a lot less time to write it on a scrap of paper than http://blogs.discovermagazine.com/badastronomy/2010/06/07/hard-to-port-eject-goose-eject/.

Which of those URLs would you rather type on your keyboard? Or worse, on your mobile phone?

*In this case, I mean making it really short and cryptic. There are plenty of reasons to keep links readable and sort of short.

I’ve deleted redundant or trivial items, split some digests by topic, tagged, categorized and titled the rest, fixed typos and expanded abbreviations, reformatted quotes, links and lists, imported photos, and more…all in an attempt to make the archive a little more useful.

After trying to unify some of the more eclectic mixes of unrelated one-line remarks and links, I’ve decided it’s time to stop automatically importing “tweets” to the blog. Sure, the digests maintain quantity, but I think it’ll be better to keep the quality up instead. What makes a good status update doesn’t always make a good blog entry, and I’d frequently find myself either staying up late to edit that day’s “Line Items” post or rewriting it the following day. (Plus I was always worried about a bug in Twitter Tools that would cause a duplicate post about 30-50% of the time.)

I think the blog will be better off if I copy, expand or skip stuff from Twitter at my own pace and put it in a more suitable format to begin with.

For the longest time, I figured Twitter was little more than a social toy. But after signing up two months ago, I’ve completely changed my view. Here are five lessons I’ve picked up.

1. There are many ways to use it.

Twitter asks the question, “What are you doing?” Some people answer that, and post things like, “eating dinner.” Some people ignore it and post other thoughts. Among the uses I’ve seen:

  • Running commentary throughout the day.
  • Random thoughts.
  • Announcements, particularly bloggers announcing new posts, or news sites announcing new articles.
  • Hey, look at this link I found. (The classic linkblogging post.)
  • Conversations with other users.
  • Even a story told one line at a time. (@Othar, a side story connected to Girl Genius)

It can replace a blog, or complement it.  Mine started out just as another feed for updates, but I quickly realized I could post small stuff on Twitter and save the blog for the long posts like this one.

I’ve seen some people who post 20 times a day, and others who post once or twice a month.

2. Writing short posts can be liberating.

You don’t need to think of a catchy title. You don’t need to worry about structure. You don’t need to worry about fully developing an idea. And the rapid-fire nature of the site gives you a sense that you’re only worrying about now. No one expects you to be profound. All you have to do is jot down your thought and fire it off.

3. Writing short posts can be frustrating.

One of my high school teachers used to quote this adage: “If I had had more time, I would have written a shorter letter.” It’s easy to ramble. It’s hard to edit. And it’s really easy to run into that 140-character limit, especially if you’re including a link (even if you use a URL shortening service like tr.im).

Sometimes I think what I want to say is short enough to fit, but I find myself spending several minutes trying to rephrase it, use shorter words, cut out unnecessary phrases, and, if I have to, abbreviate words just to cram it into that tiny space.

On the plus side, the result is usually very concise.
