"Twitter is ruined," writes @usatodayopinion columnist Rex Huppke. Huppke's (satirical) answer: HOLLER. He explains it as "a sensible and engaging real-world Twitter replacement." "Once you subscribe, you send me a telegram that includes your address and I'll send a return telegram letting you know where the nearest street corner is. Then you just walk to that street corner and get to hollerin’!" Huppke writes. "HOLLER combines the hipster appeal of retro technology with the modern consumer’s need to pay for something they could just do anyway." As a growing number of Twitter employees resign after a Thursday deadline to remain at their jobs or quit, many question if this is the end of Twitter. Do you think Twitter will be gone and what online platform will you use instead?
