This are my predictions for 2008 (btw nothing really special) :
1. The Iphone will blast all the existing phone companies and GPS systems too and it will redefine the use of the day to day internet.
2. googlers will loose a lot of key members (departures)
3. Dedicated social networks will grow up (for healthcare, for patients, for cars lovers, movies and tv shows lovers, ...)
4. Semantic search technology (powerset.com) will be beaten by human social search engines (mahalo.com) for the same reasons as today, mahalo answers with better results than a standard search engine (google, live, yahoo, ask)
5. 3d shopping websites will rise up (potoroze.com (hi sebastien 
)
6. Year for personal videoblogging and quality video contents (hulu, new players and professional-driven models)
7. Turnover will start again in many companies due to the "Internet rebirth"
8. RIA and accessibility will be good friends
9. Our personalized giftcards websites like loveticket.com will grow up
10. Facebook will lead the advertizing industry and become the #1 website worldwide
