First off, I had some expectations of what I wanted Google Wave to be. But so far, it hasn't met them yet. Therefore, I'm not too active nor frequently visit my Google Wave after the first few tries, unlike Facebook. Not all my friends or family have Google accounts (hence they have no access to Wave). And I haven't added any Wave Extension I like nor find useful (for me) yet either.
My primary expectations/Google Wave wishlist:
- integration with my blog/s (blogger.com, multiply.com) whereby I can post my blogs via Google Wave
- integration with my online photo albums whereby I can provide links to and -- even better -- allow fellow Wavers to view within Google Wave photos I posted to another online photo album
It is fun though doing collaborative activities in Wave. I see my friends and fellow Wavers typing in their responses to a specific wave in real time as I know they've also seen mine and it's like we're all just in the same room but we just don't happen to see each other.
For now, I see Wave being better used by groups/members pursuing a project together, or doing collaborative research (i.e. the scientific community) where up to the minute results and posts to be shared to multiple relevant Wavers is of the essence.
As for me I'll probably only be more active in Wave if my most frequent online activities are integrated with it quite seamlessly (blogging and uploading photos to share). Until then, I still love multiply.com for photo albums sharing within a blog. hehe!
