2007 is here, and so it is time to look ahead and provide some wild guesses as to what will come.
Overall I think 2007 will be the year of transition. In the last couple of years we have seen a lot of activity with AJAX, Web 2.buzz (usually referred to as Web 2.0), the social web etc.
In 2007 we are going to see several kinds of transitions.
2006 was all about "2.0". It started with Web 2.0, but now we see all kinds of "2.0's". It will still make headlines with the press, but for those who really matters it is the mark of a failed experiment - and of good intentions gone bad.
If you call something "2.0" in 2007 you will automatically label it "I failed" (and do not even think about calling it Web 3.0, unless you want to sound desperate).
BTW: You might consider your exit strategy...
Atlas, Microsoft Expression, Windows Presentation Foundations, are all applications/systems with incredible potential. We have already seen a few (mostly poor) examples of what to come.
The main reason I am excited about this is that Microsoft is way ahead of the pack in terms of rich media internet applications. Although they have not really made anything really spectacular yet, the very existence of these new technologies will get people moving.
2005-2006 was really about allowing people to share and communicate through an amazing amount of new services. But, although a few of them offer API's none offer interoperability with other systems. What we are currently seeing is a fragmented internet - desperately in need to be cleaned up.
Since 2007 is a year of transition, there will be a somewhat less activity until the trend-makers come up with something new.
xHTML + JavaScript will get into trouble
2005-2006 was really the rebirth of xHTML + JavaScript, but as web applications starts to get more and more advanced, people will also realized that these technologies is not up to the task. WPF and Next-gen Flash will gradually take over as the development platform of choice (with emphasis on gradually).
We already see this in many computers game and with Second Life - both something that could not work without the internet. In 2007 we will see internet usage increase tremendously as the basis of other applications/systems.
BTW: Do not confuse this with the Web (the thing you see with a browser).
