Man, that's a lot of time since you've last been there! Welcome back. I'm sure with your background you'll find your niche fairly soon. There are still active Zoner factions (primarily OSI and Phoenix), but there is Pennsylvania Liberation Front if you're looking for a more radical twist.
For a generally roleplay-heavy faction I would suggest Starfliers, Technocracy of Auxo, Bristol Constructions, Ageira. RPA| Mollys, Kongsi Syndicate if you feel daring and wish for an unlawful twist. There's also occassionally appearing Lovelace Circle. A bit specific and not my cup of tea for the Lane Hackers, but definitely appealing in their own way.
But, wherever you end up - remember to take it nice and easy to enjoy yourself and have fun.
