1. Boring business names.
“twitter merges with plurk to form plitter, which is purchased by facebook (which breaks it) and renamed plitterface, at which point google creates an Open Source API app that adds digg to your plitterface, creating piglitterface.” – Overheard in Second Life
This may seem trivial, but company names and product names will start to get more serious and traditional as the more staid elements of the economy (government, financial sector, etc) look for social media partners/providers. Also, hopefully the term “social media” and its variants will go away.
