Posts about ICQ have been trending on facebook. A lot of 70s and 80s people would have an account or a few to connect with friends. There was a say that people ask for ICQ no before phone no and there was a song utilizing ICQ no as the song name.
MSN replaced ICQ subsequently, and then we have started replacing MSN with whatsapp and facebook. I don’t think the comeback of ICQ is going to be long lasting but it does bring back the memories of many 🙂
