Twitter is opening up Direct Messages to longer message lengths from 140 characters. The developer forum that talks about the change doesn't actually define the upper limit of the new message length but MacWorld says that it's 10,000 characters and there's no reason to disbelieve their claim.
According to the forum post the update is coming in July. This does make us wonder though, how far behind could it be for a lengthening of standard posts?
If Twitter does lengthen standard posts we see two outcomes for healthcare marketers:
- Longer posts may mean that brand claims will be possible on the channel, with abbreviated but meaningful ISI embedded in the post itself
- Twitter will lose some of its differentiation from Facebook, and if that happens the likely outcome would be stalling of growth or even abandonment
For healthcare marketers running social programs, this means that private conversations with patients can now be much more detailed and compliant.
