Snapchat's meteoric rise made one thing abundantly clear -- the market would soon be flooded with copy cats. The next major player to try and drink Snapchat's milkshake might be Instagram. A banner introducing Bolt, a service for "one tap photo messaging," appeared at the top of the company's mobile app last night. The announcement was quickly pulled, but not before several people grabbed screenshots and started passing them around on Twitter. Unfortunately there's not much more detail to share at the moment, but the move will definitely raise a few eyebrows. For one, it would seem like a trivial feature to simply integrate into the existing Instagram app. Secondly, with Facebook's Slingshot already offering ephemeral photo and video messages, Bolt seems like a duplication of efforts. Of course, there's always the chance that Bolt will offer some truly unique twist on the format and shove pretenders to the media messaging crown aside.
