Just stumbled on this SE a few days ago, and It has inspired me to get into riddles and puzzles myself. This is the second riddle I have ever written, I imagine it should be pretty easy (Though that is easy to say when I wrote it).
I will add hints as time goes on, if I need to. Good luck, have fun, and any feedback is much appreciated.
With some help, I'm very smart, alone I am quite dumb
My convenience is unrivaled, to my lures you shall succumb
I come in many shapes and sizes, I'm the cause of much debate.
Those who know me well, they love me. The clueless tend to hate.
Ever changing, never ceasing, I won't soon say good-bye,
If you think you know my name then tell me, what am I?
