After her separation from husband Pawan Kalyan, former model and heroine Renu Desai got active on twitter circuits. Thick and fast, she shares some info on the social site with her followers. Today she expressed her unhappiness over her followers not showing interest in social causes.“If I post a pic of Aadya & Akira it gets a lot of retweets. My Save Water tweet was noticed only by few! WATER is very imp for ourselves only..! If I use Twitter to post cute pics its all good but if I raise a serious issue like Water shortage it's called 'taking tuitions'..pointless!", she shared today, expressing her dissent. People generally follow celebs for entertainment and this particular scenario proved it again.
