Check out the article 11 crucial consumer trends for 2011 by trendwatching.com! They have some, in my opinion, very interesting suggestions.

My personal favorite trend is R.A.K. aka Random Acts of Kindness. As an example, they cite Interflora in the UK which has launched a social media campaign via Twitter.  The campaign consists in monitoring user accounts and if they happen upon a tweet à la “alarm clock didn’t ring & missed my flight” or “my boyfriend forgot our anniversary”, Interflora will offer to send you a flower bouquet to brighten up your day.

A great idea!
