While it appears in the next season Robert Knepper is playing something akin to a cult leader, it occurs to me that smart Sylar could just as easily create a cult of his own.
...a real very, scary SARMY. How would it get started? Easy.
By creating his own church, or taking up a 'cause and providing a structure for runaways ala "Fight Club" for young people like Luke. Starting with runaways, the poor & foster home kids kicked out on the streets looking for sanctuary. In short, like Jim Jones, David Koresh or Manson.
And using the internet he could easily grow such a cult.
But Why? We all know he's looking for powers, what better way to get adoring worshippers to do it for you? He provides employment or at least a roof How? Selling soap as in "Fight Club" ? or in the production and selling of Sylar watches perhaps? He provides for their material needs and in turn they comb the country looking for 'Specials' for him.
Sylar could just as easily say the other 'Specials' are demons and must be ferreted out & hunted down. Its something Nathan did with the government but with a legion of young people under his spell he could do it far quicker.
If he grew his cult he could potentially have thousands of eyes on the internet, scanning newspapers for "mysterious" happenings.
I could see him taking this route if Nathan's way to the White House seems blocked for past mis-deeds.
Its just another way to Power and nearly God-like status. So Politically he could take the White House looking as Nathan but appears as Sylar to his followers who are on "the inside"
I hope you find this scary. What else do you think?
