MG Siegler:
Of course, we can rest-assured knowing that Twitter is very likely are not this foolish. After being in business for a full five years, they must know by now that their strength is not to mimic every just-launched and hot-right-now new social network (in this case, Google+). Their strength is to remain true to what got them to my where they are now: simplicity.
My sentiments exactly, just more spot on.
