Luke Wroblewski for Google:

When someone shares something new to a space, the conversational view lets you see what the group is talking about without missing a beat.  And if you ever want to find something that was shared earlier—articles, videos, comments or even images—a quick search lets you pull it up in a snap.

Google’s Spaces comes too little, too late in my opinion. The pitch for the app is that people need a way to keep all their shared items and conversations in one convenient place. The issue with that is that people have found solutions to this issue. Current messaging apps do a pretty great job of keeping these conversations organized to that point where Spaces isn’t needed.

That said, Spaces isn’t without merit. The use of Material Design is solid, even on iOS. The app functions well and doesn’t need much from users to get up and running. The baked-in Google Search and YouTube is nice and makes the experience pretty frictionless. This is something the company is getting more and more interested in doing as we’ve seen Search make its way into Google’s recent Gboard iOS keyboard replacement.

In many ways, Spaces is a rethinking of Google+’s Collections feature which, like parts of the social network, hasn’t seen a ton of traction. Sadly, I feel like Spaces may be destined for the same fate. If you’re an active G+ user, Spaces might be for you but, for the rest of us, there isn’t a ton of reason to move the party over to this new app, at least not yet.
