[BBC] – Twitter’s rolling out a feature which could instil fear into your social media hearts.

It’s letting you search for every public tweet since its creation in 2006, roughly half a trillion posts.

On the one hand, it could be seen as a helpful and extensive tool for information.

On the other, it could flag up any user who may have forgotten about a potentially embarrassing post from their distant past.

In theory, it means anyone can look back at your FULL tweet history.

If you so wished, you could go back to the beginning of your timeline and see just how mundane – or thrilling – your early tweets were.

Perhaps more interestingly, you can search through your friends entire history, as long as they were posting publicly.
