Ever wonder, “where did that tweet go from so-in-so from three weeks ago”? Or, “where is that link I tweeted last month”? If you didn’t add them to your favorites then the tweet may have disappeared. Here are some tools to make sure that never happens again.

Did you know that your tweets have an expiration date on them? While they never really disappear from your own Twitter stream, they become unsearchable in only a matter of days. At first, Twitter held onto your tweets for around a month, but as the service grew more popular, this “date limit” has dramatically shortened. According to Twitter’s search documentation, the current date limit on the search index is “around 1.5 weeks but is dynamic and subject to shrink as the number of tweets per day continues to grow.”

What that means is something tweeted prior to a week and a half ago can never be retrieved via search.twitter.com. That’s bad for users and it’s definitely bad for data-mining. Unless Twitter corrects this issue on its own, we have to find another solution for archiving tweets ourselves. Here are 10 ways to do so.

One of the unfortunate side effects of the FriendFeed acquisition is the very real possibility that the company will eventually shut down its servers. There are many reasons why this is upsetting – the site’s users now have to figure out how to extract everything from their natively posted content to their comment streams – or lose them forever. However, one of the most disappointing losses will be losing FriendFeed’s search feature. Since the service functioned as an aggregator of the social web, most users piped their tweets into FriendFeed, making the site a searchable archive of tweets which were still available no matter how old they were – quite unlike Twitter’s own search. But if FriendFeed is going to disappear, we need to consider some alternatives.

1. The Archivist: A Desktop Tool for Archiving Searches

The Archivist is a Windows desktop software application built by members of Microsoft’s Mix Online team. With this program, you can create Twitter searches which will then be archived to your PC so they can be data-mined by you at a later date. Recently, the program was updated so that it can be minimized to the system tray – especially helpful for when you want to track a Twitter search over a long period of time. They also added a data visualization feature which calculates who’s tweeting the most about your topic.

2. Twapper Keeper: Archive Tweets Based on Hashtags

Twapper Keeper is an online tool which archives tweets based on a given hashtag. Once you set up a query, Twapper Keeper will periodically scan Twitter for that tag and then archive the tweets it finds on its own servers. Tweets are scanned approximately every 5 minutes but that can vary based on the velocity of the incoming tweets. Once archived, you can then organize the tweets into categories of your choosing which show up on the right-hand side of the archived page.

3. Twitter Tools: Archive Tweets in WordPress

Twitter Tools is a WordPress blog plugin which integrates your blog and Twitter account. Once installed and configured, the plugin can be used to both Twitter links to your blog and to create posts which contain your recent tweets. While this is handy for the WordPress blog owner, keep in mind that post after post of “Today’s Tweets” isn’t all that appealing to blog readers. You may want to create a separate blog for this if you intend to use WordPress as your own personal Twitter archive.
