Just read an interesting post by David Armano which speculated about six important trends for social media:

1. Social media begins to look less social
Lists and filters will make the social web more exclusive

2. Corporations look to scale
Companies will turn to large scale implementations to enhance their business

3. Social business becomes serious play
Incentives will be mixed in with social media to increase stickiness

4. Your company will have a social media policy (and it might actually be enforced)

5. Mobile becomes a social media lifeline
…because companies will be controlling web access more tightly

6. Sharing no longer means e-mail
Share through Facebook and Twitter (and the like) buttons will become ubiquitous
