Some of us – the early adopters – think Facebook and Twitter are already over because of Friendfeed, the new hot web 2.5 app (It’s up to you to decide if it’s already 3.0 or still 2.0).

Blogs still fight against text spams with unreadable-but-still-hacked captchas while Seesmic delivers video comments to the masses.

We thought XML would rule – and more important, unify – our communication needs. But JSON is in fact easier – and smaller -.

Google still doesn’t understand Flash embedded on webpages but it takes pictures of our streets in Paris.

My iPhone doesn’t support MMS. Who need them anyway when everybody has email on its phone?

We all know technology is about evolving. But how can we talk so much about sustainable development with such low half-lives in IT? How are we supposed to build sustainable business models with such versatility?

Don’t forget we – still the early adopters – are not mass market and what excite us may disappoint anyone else. I do use friendfeed everyday but even if I don’t use Facebook anymore, I understand there may be a gap in valuations: Facebook is not dead, it’s even one of the biggest web applications.

Being the big buzz of the day on TechCrunch doesn’t guarantee commercial success. Even more, being popular among geeks tend to be suspicious. So don’t predict anything based on popularity in this particular community.

It takes time for a new technology to go mainstream. Don’t call it disposable – or dead – too soon !
