Keep that pinch of salt handy.

The strengths of the internet also tend to be its weaknesses.  For example, you can put stuff on there pretending to be who you want, but that equally means that you can't assume that people are who they say they are.  Recent case in point is a blog supposedly written by a Syrian lesbian woman - it now transpires that the author is in fact an American man living in Scotland! So the internet surely is a wonderful thing, but caution is advised.
