Their newest app, Glide Engage, is a mobile and web microblogging and collaboration tool that launches today and supports 1,400 character posts (not 140), file and media sharing, and distribution options to simultaneously post on Facebook, MySpace, and Twitter.
With Glide Engage, users can can consume media, bookmark links, send files, share photos and videos, and post updates of up to 1,400 characters in length. Shared files are synchronized in typical Glide style, and users can share, view, and edit pretty much any file or media type.
It's not exactly a Twitter competitor, but it does support a follower model — engaged are people who follow you, engaging are people you follow — with a stream of activity, so users can follow each other to keep up with the shared updates of other users. There's also a way to send private messages, using the Glide Engage Inbox, but with the larger character allowance, it's more akin to your Facebook or email inbox then your Twitter DM Inbox.
Glide Engage also supports public or private discussion groups that come complete with a contact manager, group inbox/outbox, and file management. There's also the added ability to tap into other Glide applications like email, groups, meeting, and presenter, to create professional workspaces, or real-time collaboration hubs for online meetings.
