Life as an Artificial Lifeform

Today I got the third invitation for a new "Web 3.0" applications "private" "beta". This one was for a service called twine and is basically a way to organize digital stuff - as wide as you want to describe stuff.
It has made me thinking why I am reluctant to spend more then 20 minutes with these services, why I don´t have a flickr account, why am not contributing to wikipedia and I have a conclusion that any of these companies should take to heart because I sincerely believe that I might not be the only one with this thought.
In a time where time seems to be the most important resource a person can posses I want to spend time so it benefits my future - and with that the future of the planet as well (because without it I wouldn´t have one). I love collective wisdom (as in wikipedia) I benefit greatly from it every day, but I have also been around the net long enough to know that spending hundreds of hours on forums, wikis etc. is a lost cause if this information you give out does not stay in your control. I don´t mean that I want to control the flow of this information, also I don´t want to control its death but I want to stay in control to keep it alive. I have been using the net in some form or another for about 13+ years now and I have seen a lot of the information I gave to it disappear forever into some unknown electric universe. Now companies are craving to organize not just my words but my pictures, videos, pfd documents - basically my knowledge - so that others can access it and find it easily - the so called web 3.0 or the semantic web. I applaud that thought as it will ultimately lead to a greater collective wisdom, but I also have shivers down my spine when I think that in the future I collect all my information on somebody elses machines. As I have just layed out companies on the web tend to diy sudden death, or swallowed up by corporation that have ill intends (yahoo->microsoft f.e. where delicious hosts tons of my precious links I collected over the years) or a change of leadership makes the wrong decisions, or they have a failed backup plan and all data is lost (just happened with a big internet provider in the US who lost mails from about a million mail accounts). Its just too much trust I would have to give out my most precious resource - time - to someone I don´t know, someone who could morph into someone else, someone who could become evil that I don´t want to be affiliated with. So I don´t think the solution for me is called twine or powerlabs or whatever - I think the solutions has to look different.
I want to have control over the longlevity of my information - yet I still like the idea of a collective organization of all knowledge in the world. So I see a decentralized structure of knowledge sharing as the better way forward. You know all that is needed is a standard that would put all the knowledge on my servers out in the open - to be freely harvested by semantic web engines. I can then keep my internal organizational structure, use tags or hierarchies or groups or whatever to let the outside world know what these documents mean and then the web 3.0 companies can just take this and put it in pretty easy to use interfaces and connect with information with other people. If one of those companies goes bust you still have not only the information but also the organization of this information and a different service can come along and use it all. Its sort of like the Open Social platform that tries to do exactly this with social networking (again I want to be in control to whom the time goes that I spend without a lock in and without a feeling that I loose everything).
So for Web 3.0 to really kick off you need something like an OpenSemantics framework that can be implemented into just about any information collecting tool out there (blogs, wikis, even forums). Something that helps you tag, organize, auto-organize your information and makes it available to others out there. It has to be an open source standard that is extendible to a lot of information carriage formats and probably it has to be pushed by something like the W3C to give it enough traction to gain any footing against these thousand of new "web 3.0" startups.
Until then I refuse to give out more time to any of these things no matter how many "private beta" invites they send me.
