Alexander van Elsas compiled an excellent list of 10 reasons why Google just reinvented online communication. You should read that blog post now, if you haven’t already!

I do agree that Google does Wave the right way – it’s all about openness, Alexander’s points 2 and 3 should make most critical users and developers happy.

But then Google still has the business advantage of having all aggregated data in their silo’s – they will be the exclusive owner of virtually all communication data in the world. This gives them enormous business advantages in terms of finding out what people are discussing, right now. All this can be put in perspective with data mining of all previous communication. The logical exploitation is ever more targeted advertising (adding location, local time, mood, communication partners and such to the expression). But being able to watch real time trends in high resolution, fine grained up to the user level in the context of their social network will likely enable entirely new business models, which we can not even imagine right now.

Does this matter for the individual user?
Maybe, privacy is potentially at risk even more than it is now. Whatever will happen, great power comes with great responsibility and the slogan “do not evil” applies more than ever before.

At the same time I’m really excited to see this happen and will most likely join Wave as soon as it becomes available.

What did Scott McNealy say again? “You have zero privacy anyway, get over it” . And that was ten yars ago.

What the trend

Update: yes, there are more such services now, I just discovered tagdef.com which does more or less the same. And is much less complete as of late Aug. 2009. Their complementary twitter account is @newtagdefs.

Since Twitter search officially launched, Twitter trends have become an essential part to keep up with the service. These trends are shown on every search page.

Many trends are marked by the often cryptic hash tags (e.g. #www2009 stood for the WWW conference, 2009 edition.

But also regular terms emerge in the trends if people are using them often enough, for example names like Susan Boyle become real Twiter trends this way.

In many cases, looking at the trends will give you a quick impression what is hot right now in the world. But sometimes terms and hash tags are not obvious at first glance, if at all.

A new service, whatthetrend.com, has been launched to solve this problem. The site shows the latest trend terms, along with a small user-editable explanation what the trend is about. This looks a lot like the awkwardly named technorati experiment WTF (intended to be a funny acronym for where’s the fire).

Clicking on such a trend displays related tweets, news and photos, very neat.

Of course, whatthetrend comes with its own @whatthetrend twitter account which announces new trends and invites followers to explain them. And you can also use wttrend.com to save on your 140 chars limit.

I really like this service!

Some more random observations around Twitter trends

Timezones

The local timezone of an event is often very relevant for something to become a trend. Right now, #hksummit is trending (Apple event in Hong Kong, at local time somewhere afternoon). With Twitter becoming more and more popular, geographic restriction on search/trends might become useful for disambiguation and better signal to noise ratio when following local events.

Spam

Spammers are starting to abuse the popular tweet terms and post tweets with just these terms, together with their spammy links.

There is one twitter account (which I won’t mention here to avoid free publicity) which does just that: take all trend terms, convert them in a Amazon search query with affiliate code and post a tweet, many times per hour.

This was first discovered by the @paggr folks during #www2009. They are now trying to keep the spam out of their system, yet another arms race against spam has started.
