HootSuite is less than useless, as Twitter Terms of Service prohibit anything that might take eyes off of Twitter.
Disclosure: I am an engineer with HootSuite
Hootsuite is also not just for Twitter; they allow access and control of multiple social profiles. Granted most people use it only for Twitter, but the fact remains, they have a product people are willing to pay for.
I can't really envision a scenario where Twitter killed them, but if you can, please share.
They enter the market with a competing product.
for a classic example of how even in the most optimal scenario, the platform doesn't always win when it tries to compete with the ecosystem.
Schedule tweets are definitely awesome, we certainly are not using them enough. I assumed Companies like Buffer would be more specialized at that use case and had been meaning to check them out for that. Guess I should actually try what Hootsuite has built in.
