MetroTwit Loop is the beta edition of MetroTwit Twitter client for the Windows platform.
The developers have made one significant change in the latest update released to the testers. The app has switched from Embedly to NoEmbed.
This should help in improving the performance of previews of embedded videos and photos in the app.
There are other issues with Embedly of course… The free API is limited and the app is gaining enough popularity to make it a cause for concern.
