I got many accounts on pinterest ranging from 50k-100k followers. I get hundreds of repins, likes etc. I have just started to take tumblr seriously but its too difficult to gain followers on Tumblr. Is it a good idea to drive traffic from pinterest to tumblr and gain followers. has anyone tried this?Also i want to ask if anyone is interested to trade his tumblr account with 20k+ followers with my pinterest account with 50k followers.
