The number of followers you have on Twitter has always been an ill-advised way to measure status and influence. It looks impressive, but in many cases is not indicative of anything.
If you have 100,000 followers it certainly appears that you’re popular, and that you must (in some way) matter, but virtually anyone can reach that number – all you have to do is follow 101,000 people yourself. The actual value of building a large community via reciprocal following (certainly automated) is often very low – by definition, these kinds of networks are not (and likely never will be) all that engaged.
In some cases follow count absolutely is reflective of influence.
