Google announced that they won't continue developing Wave, but I can't say I'll miss it. I must admit that at the time that Wave was launched, I got caught in the hype around the new Google service and was desperately asking for an invite. Once inside, the question was "OK, so now what?". And just a couple of weeks after the launch, I had forgotten about Wave.
Now that Wave has been discontinued, maybe it's time to look for an alternative - an online communication tool to speed up and improve the workflow in collaborative projects. That is, if you really used Wave at all and need a replacement for it. Here are five Wave alternatives:
Shareflow - a group communication tool that eases sharing of documents, media files, ideas and more with a specific bunch of people. It features real-time chat, supports posts and replies via email and works from your mobile phone without having to install an app. You get 1 GB of free storage space, with Premium plans starting at $20/month for 5 GB.
Slatebox - More than a tool to exchange messages, Slatebox helps you create online mind maps and diagrams, and share them with collaborators, coworkers or students in no time. It works with all main browsers (Internet Explorer, Safari, Chrome and Firefox) and lets you embed maps anywhere - no Flash or other plug-ins requested.
Dabbleboard - A collaboration tool that's centered around an online whiteboard. You can create mind maps, write text, insert arrows and predefined shapes, and even draw freehand. Dabbleboard offers a free, feature-limited version and also paid plans with more advanced functionality, starting at $8/month.
Microsoft Sharepoint - Microsoft's contribution to online collaborative apps is Sharepoint, a tool intended to make group work easier. It helps you set up a website to share information with collaborators, generate reports to keep everyone up to date and work together on documents from start to finish.
Scribblar - A powerful tool for online communication with a bunch of interesting features: multi-user real-time whiteboard, live audio, embedded text chat, support to share images, and more. Scribblar is free, with a Pro version (including white label integration with your brand and logo) for $99/month.

Notice there were no email services listed? Never quite sure why people listed wave as an email killer.
Check out Sync.in - http://sync.in It is a web based word editor to collaborate in real-time. We use it to brainstorm and work on documents simultaneously, in realtime. It has a cool desktop app through which I access the notes created with Sync.in. It is a fantastic tool and a great alternative to Google Wave.
Sam, it was listed as an email killer because it was supposed to work as both an email account as well as a social messenger. You were supposed to be able to email people but also talk in real time and be able to edit messages in real time to send to other people. Honestly I think it was too ahead of it's time. People weren't ready for something so advanced. People with email right now just want something simple where they can mail others, they don't want extra stuff that might make things more complex. People just don't like to try new things. That's why some people stick with Internet Explorer and Windows Live Messenger. They just update what their used to rather than try something else. Best way to get more people to use something is make it have more available features but make it as simple and easy to use as possible. Wave was just too complex for the average user. And why would anyone pay for a Wave like service when Wave's biggest appeal was it was completely free?
