That's like saying cellphones are replacing PCs even though PCs are "better." They are different. Twitter is better for some things, forums are better for others. I'm not even sure I would call a forum "social media." But you're right, Twitter is not designed for in depth conversations so if people are trying to have them on Twitter then they are making a mistake. But for sharing random little bits of news and stuff (what it was for) Twitter is superior to a forum.
"If all mankind minus one, were of one opinion, and only one person were of the contrary opinion, mankind would be no more justified in silencing that one person, than he, if he had the power, would be justified in silencing mankind."
