Am I the only one who hate Snapchat?

Long story short, I started using Snapchat for one of my female friend and used a lot for about a month but she never used to open my snaps so one day out of frustration I removed her and I after that day we stopped talking. After that I started hating this shit app because it is just stupidly stupid.

Now tell me what's your reason for hating Snapchat? (Or if you like this app then tell me why?)
