You are most certainly correct, especially if one uses the history of other sites as our guide. Reddit for instance was obsessed with talking about reddit for the first few years of its existence, there were a high number of posts where people just put up an image of someone on a bus on reddit on their phone, or someone in a class on reddit. Reddit sightings were a huge topic of discussion.

It didn't evolve into something more like it is today, with a wider variety of topics discussed until a few years had passed, and largely until after Digg, crashed and burned. The process seems to take years, however people taking an active role in promoting diverse topics may make it faster. Its a great question as to how much faster, and is actually an interesting social experiment.
