If you know that during the last few weeks you wrote a tweet that is now hard to find, twissues.com you can help.
It is a tool that allows us to backup all the texts that we sent to twitter recently,with the ability to search for them, allowing a limit of 3200 tweets in its first recovery, limit set by the Twitter API itself.
After saving the texts we can search through them at high speed, both by keyword and by hashtag, there is also the possibility of finding information on trending topics in three different countries.
Although the limits imposed by Twitter makes twissues less attractive than it might be, it can be a good option to have indexed records of what we have reported recently, even once we have made the first importation, not to lose any text published.
Remember that, in case you want to have an automatic record of everything you tweeted, there is the possibility of sending tweets to the Google Calendar at the same time they are posted, for that purpose you can use twistory.net.
