Yoono, the client that mashes together multiple social networking feeds into a single app, has released version 1.5 of their free desktop client. This is an important update for two reasons: the addition of a major social network, and the ability to manage multiple accounts on the same network.
The network newly added is LinkedIn. A popular social networking site for business users, LinkedIn allows people to network together strictly to further their careers. Its suggestions for building connections are more stringent than those of, say, Facebook.
The second new feature to Yoono is the ability to have multiple accounts running from a single social network. This is useful if you manage more than one account--for instance, a personal account and one or more for your business. These accounts appear as new icons at the far end of the list. It would be nice if multiple accounts from the same network were adjacent, or better yet, within the same icon and accessible via tab. It makes better UI sense when icons are per-network rather than per-account, per-network.
I did notice one bug when pop-up status updates were exceptionally long: The pop-up window's border moved off-screen, so I couldn't click the right arrow anymore. Yoono should consider truncating messages shown here to prevent this from happening. The same criticisms of the previous Yoono version still apply here: unlike competitor Seesmic, Yoono has chosen to use a single-feed UI with buttons, rather than multiple columns at once. There is currently no option to display columns side by side. This single-column format requires either reading the all-in-one feed, which is sometimes inconvenient, or doing a lot of clicking back and forth between the individual feeds. Many standalone Twitter clients let you run your multiple accounts side by side, and it would be nice to have that as an option here.
Otherwise, Yoono is a nice choice for the pure social network breadth it contains. Seesmic, for one, works only with Facebook and Twitter and nothing else. If you've got a good reason to have an account at several places, and want to look at them all easily, Yoono is the way to go. And since LinkedIn support is rare (the programming interface was just released), it's nice to have that integration.
Note: Yoono is also available as a Firefox add-in as well as this standalone client.
