In my post yesterday I noted the increased push by the Wave developers to make it easier for the wave community to build and deploy extensions. It turns out this flurry of activity coincided with the imminent release of Version 2 of the Wave API, announced today.

The first new feature is the:

Active API: In v2, robots can now push information into waves (without having to wait to respond to a user action). This replaces the need for our deprecated cron API, as now you can update a wave when the weather changes or the stock price falls below some threshold. You can learn more in the Active API docs.

If I understand this correctly (and I’m not a developer so correct me if I’m wrong) this means that before today, a robot in a wave might have had to wait until a user opened a wave before it could refresh the information in the wave (updating stocks etc), now the robot can initiate a wave update itself, making it possible to have robots create new blips in response to events. This is a much smarter way for a robot to behave, and should make for far more interesting and functional bots.

For a more enlightened perspective from a wave developer, check out Mastering Wave’s take on the announcement.

So what I initially thought was just a push to get developers involved was actually leading to an announcement of a massive upgrade to the API. In the end though, the aim is the same — to get developers engaged and creating interesting software to make Wave an indispensable tool.

Add the Karma Gadget and Bot to your waves and use it to rate your users (out of five stars). If users get consistently low scores, they will be automatically kicked from Waves that choose to turn on this option.

Of course there are some potential problems with such a tool: if a user expresses unpopular views in one wave and gets poor ratings, they might find themselves banned from any future wave that uses the tool, regardless of the subject. If the tool took off in popularity it could be quite horrible to find yourself on the end of such banishment.

On the other hand, if the tool doesn’t get popular it would be unreliable for crowdsourcing opinions, letting in known trolls who had just not been rated on enough waves.

Despite these shortcomings however, I would love to see this developed further (and even be integrated as part of the official spam-fighting tools of Wave), as I see great potential in harnessing the opinions of others in keeping waves free from known trolls and spammers.

One potential use case is the immediate banishment of those frustrating bots that pop up all over the place (Kanye-bot anyone?). I’m uncertain whether bots are in the firing line (Karma-Bot itself seems immune and doesn’t show up in the rating gadget). I’m also unclear about what happens if something like the public group (which can be rated) gets consistently bad reviews.

As of writing, the gadget does not carry out bans and won’t until Google implement the kick-out feature. I will be following this tool as it develops, and I’ll be looking for opportunities to use it. And if you see me on a wave that uses Karma, please be nice!

The service does not yet allow you to add users by their googlewave.com account (gmail.com only), and the permissions can only be handled through the Google Groups interface. It also seems that to avoid spam (being able to send messages to an everyone in a public group at once) users must pro-actively seek out the group wave and follow it to move it to their inbox [currently waiting for confirmation of this].

Like any Wave feature, this is still being developed and its behaviour could change over time. The Wave team have said they will continue to enhance the groups feature to make groups easier to navigate.

Well now Chrome has a neat little extension that does the same thing. Jeremy Selier has built a neat little plugin that shows you how many unread waves you have in your inbox. It checks every thirty minutes by default (at the request of the Wave team), but you can set it to check more frequently in the extension options.

Something that makes a sound, or pops up a notification box (Growl-style) would be even more useful in some circumstances (Firefox is still my main browser of choice). However, if you need a simple way to see new Wave activity without checking the window every couple of minutes, this might just be the thing.

It’s straight forward enough, add the bot and log in to the form it gives you. The next time you add the bot to a wave, the first wavelet gets posted at Posterous and it returns the URL for you to check.

Posterous seems to have the most diverse posting options of any blogging software available, and the addition of posting from waves puts it again at the forefront.

Now the bot needs to monitor comments and return them to the original wave for even tighter integration.

If you need to add various characters to your waves, and are familiar with HTML entities, then the Character Entity bot might be what you need. Add character-entity@appspot.com to your wave, and whenever you write a character (in the format &code;) the bot will happily convert the code into the correct characters for you.

Here are a few to try:

• © becomes ©
• ↔ becomes ?
• ∴ becomes ?

(A more detailed list can be found at Intuitive Systems)

As soon as we’re confident that the system can accept more users, we will add a wave to your account that allows you to nominate friends and colleagues for an account. Once you have the capability to invite people, the wave appear in your inbox.

So we’ll be seeing this eventually (goodness knows how it’s added — magic fairy dust perhaps), so don’t fret — All in good time!
