Wouldn't it be more valuable to create a twitter account for the startup and get involved? By giving time to the community on twitter you reinforce the impression that you care about the users. Respond to @messages and keep people up to date on what you're working at. If you're good, you'll get coverage through followers and retweets, and it'll be free. Maybe I'm misreading this, but promoted tweets look ripe for abuse by people who think social media is just ``another source of free traffic.'' (I've stolen that from the blurb of this article: http://blog.kissmetrics.com/social-media-abuse/. http://blog.kissmetrics.com/social-media-abuse/.) The truth is, for me, that I automatically ignore content that is an obvious form of advertising. To summarize, Perhaps you'll get more ROI with an active (and free) twitter account than with one-shot ads that cost a lot. As a final question: What is the lifespan of a promoted tweet? Are they less transient than normal tweets?
