More and more people are turning to Google Translate for simple translations. In most cases, the machine translation has improved to a level that you can get the general meaning of a piece of text.
However, like any technology, if you do not use it correctly you may get results that were not expected.
Take for example the case a retired Manchester United soccer player. He thought that he would share his activities on Twitter.

The trouble started when he used Google translate to help him with his translation.
Philip thought that he would translate into Spanish.

However, it did not translate very well and the translation had a different meaning.

Now, we thought that we would use our smart phone, with the latest update of the operating system and version of Google translate to see if we could reproduce the error. We could not, so we were wondering whether it was user error or an older version of Google translate that was used.

We received different result. No harm done. However, if the tweet, written translation or the website translation needs to be accurate, a human translator is still preferred.
