About this update

I've merged the Dbase and Stats categories with DATA 2.0, the Dig category with RATE 2.0, the Legal, PSP and DRM categories with VAS 2.0, the R&D category with COLLABORATION 2.0, and the Vocubalary category with OFFICE 2.0. I've relabeled "Portal 2.0" to "STARTPAGE 2.0".

BOOKMARK 2.0 - Update

This is one of the most crowded categories, but it's not onedimensional at all. Many bookmarking concepts cross over to or have symptoms of e.g. link bank concepts, notepad concepts, Digg-like concepts and NEWS 2.0 concepts. Since the fall of 2006 I only add websites that have original features or a remarkably high quality.

BROWSE 2.0 - Update

No browser wars to be expected in this generation of the Web. I am aware that there are some more browsers in the Mozilla/Firefox school - AND numerous cool applications in the same tradition - that I don't report on in the other Everything 2.0 categories. But I'm simply too addicted to Opera's browser to look further into this. Any Mozilla/Firefox correspondents among the readership of this blog?

COMMUNICATE 2.0 - Update

COMMUNITY 2.0 - Update

Since doing things together is the most important denominator of Web 2.0, you'll find many more symptoms of community forming in other categories. But COMMUNITY 2.0 is still a HUGE category. The funny thing with communities is that only few people really know what makes them tick. Finding a theme that makes people unite around a common interest isn't that difficult, but keeping them there - happy and active - and finding a sustainable reason to ask some money for being part of them (or to find other revenue streams) in most cases is still a challenge.

CRM 2.0 - Update

In a world where more and more of the same is becoming the most compelling business proposition, it is extremely hard to make a product stand out in the crowd. We've worn out all of our famous 4 P's long ago - until the level where only rubbing in our brands into the brains of our target groups seemed a sustainable way to distinguish ourselves. But brands are becoming less and less interesting to our customers. Because, once again, all brands are becoming more and more of the same boring same. Therefore I think branding is also a dead end track.Customers want a good product, or a good service - nothing less, nothing more.Up till now we have been using - or abusing - technology in the same way we abused marketing communications - namely mainly as a means to rationalize our operations. To undress our services to the bone. To make our operations more efficient. To make our sales more effective. To improve our margins - preferrably without adding value to our delivery.Probably one of the most destructive abuses in the history of business has been in automating customer services. Where concepts for self help are presently more popular than concepts to improve a customer's experience. Where premium rate voice response systems lead us into waiting queues, and - only if we're lucky - into the hands of students who read their answers from computer generated Q & A scripts.What's so entirely wrong about these concepts, is that they completely ignore the fact that only a small percentage of our customers are in fact self sufficient, and even a smaller percentage want to be self sufficient. We've always known this. The art and science of direct marketing has learned us since World War 2 that only a minor part of our markets can be developed through customers who don't need a normal dose of service. Nevertheless, we're presently trying to push complete user bases into the lame claws of our CRM systems.What most people really want is simply to get appropriate service, especially when they need it, the moment they need it. More service. Better service. Service that makes their lives easier instead of more difficult. Service that takes away hassles. Service that enables them to spend their precious time on things that are worth wile. Service that honestly tries to give them a better customer experience.In a future where we will dominantly have to live with one person markets, we'll have to live with customers who don't accept that they are shouted at, through advertising, and who won't accept that they have to maintain a dialogue with a software. The future of commercial communications AND of services is in H2H. Human to Human.*"Social CRM" or "Customer helps Customer" already is a widely spread practice in the world of consumer forums. Many of these forums and boards are excellent exponents of "Web 2.0", although they're often much older than that term. Most of the solutions below are aiming at reducing customer delight; only some elements of these solutions and cases may contribute to a better Social CRM practice. This niche is largely open for new concepts!

DATA 2.0 - Update

Since databasing is one of the most important niches in the software market, it's surprising how few pure dbase players I've found so far. Am I missing something? To compensate this a bit, I've dumped my research on treemaps - an attractive trick to present complicated data in one view. Furthermore, many interesting things regarding the presentation of complex data are going on in all kinds of mash-ups...
I've added the former STATS 2.0 entries. Web sites in this category help you to track, trace, analyze, optimize & report on the usage of your web page.

DATE 2.0 - Update

The links below only represent a fragment of the dating market. Although I think that dating isn't even really Web 2.0 (1 to 1-sharing can't be very social, isn't it?), the sector is interesting because it's quite mature, a lot of money is going 'round, and some of that is spent on innovations that sometimes spill over to real 2.0 categories. Of course a lot more flirting & dating is going on in the category COMMUNITIES 2.0.
