Recently I blogged my travel to Maddur here and twitter shows a preview of Sholinghur railway station in the photo. Interestingly I haven’t mentioned about Sholinghur anywhere in the post. Except the subtle fact that both places are Narasimha temples. However there is a difference. Sholinghur is Yoga Narasimha and Maddur is UgraNarasimha.
Perhaps Twitter developers are best to answer the query based on their preview algorithms.
