Not a chance for me. My logic is that when grandma moves onto the social media platform, that's the death knell. I don't know anybody who's used FB a lot in the past that's using it more now. Everyone I know with a job is using it less than before and trying to do something more constructive with their time. I'm in that group. I've already caught up with the old friends, and it's not that they're getting stale, but there just isn't enough to share every day. I haven't seen FB put out any trending numbers on average user session hours in the US, but if they did I would bet the trend would be downward. Now that may not jibe with what's happening in other parts of the world where it's in earlier phases of adoption. But what has FB focused their literature on? Number of users. But just to prove my point, here's a link that's worth a read:
Second: What's the FB app development landscape? When developers are building apps that automate a lot of what caused you to be on there doing manually, that means less time on FB, less ads viewed, and less revenue. My thinking -- if you want to talk to friends, even if they're at the next table at Starbucks, you can always skype them. And if I were going to invest, it would be a VERY short horizon -- maybe 1-2 weeks at most, then if it appears to top, short it until it's dropped 50%.
