The way I look at it is Leslie kept just enough of Sense to keep the Rom completely functional and cleaned out the rest. She shoots for a release grade product and knows when she is there and stops. I imagine there is a list of silly things that could be changed, but the user can do that. I ran Harmonia 2.x on an OV for months without a hiccup. I would not be surprised to find out that a lot of OV owners followed her here since last June.
That is pretty close to it.
I've described it before as "the rom Virgin should have released".
I don't try and put everything including the kitchen sink, it's not a Cadillac, it's not a Ferrari, it' a Honda Accord. Super reliable, everything you need, nothing you don't and fast enough. Though that is arguably a bad analogy in some ways because my Accord left me stranded more than any other car I've owned, including two BMW's and several very old pickups.
I do updates as needed, usually just to update or tweak something I think could be better, like had the voicemail update been worth keeping (I hate it), it might have triggered an update, which would have had some other very minor changes as well. Otherwise, once the rom works really well, I try not to mess with it too much. Not just because there is only so much I can do, but it strays from the point and can destroy the reliability. Some people just want to use their phones, not play with roms or tempt fate, which is why many use Harmonia during the week, and play on weekends with the "latest and greatest".
As for users following me, yes, several people did go buy Evo V's almost right away, some because of my rom and for others it was just a selling point when they went to upgrade. Many users are extremely loyal to the dev of their favorite roms. Personally, I don't like the idea of putting that much faith in one person's ability, particularly mine.
Which is another reason for not including a ton of mods, despite what many think, I don't have the skill some of these others have. While I can do some things other devs can't, they can do a lot I can't. I'm not a coder, I can research, file swap, tweak this or that to achieve my goals, but really digging into code and writing tweaks, that's their realm.
