And the irony is the spammers did such a good job of forcing people off usenet that there were so few people left the spammers gave up bothering and moved on to more lucrative enviroments to screw up. The upshot is that usenet is actually quite usable now, though NNTP servers are slowly disappearing sadly.

"Rendering HTML is actually very difficult,"

Rendering core HTML has been a solved problem since the 90s. HTML5 obviously adds complexities but other vendors have managed without a total rewrite. Perhaps MSs rendering library was rubbish to start with.

"user profiles, bookmarks, system integration"

Whats all that got to do with rendering?

Just how many have their been over the years? Just how hard is it to render HTML?

Or is it similar to the move away from skeuomorphism with GUIs - its just arrogant new teams trying to prove that they can do better than previous teams whose ideas are "past it"? I've seen this pointless reinventing the wheel so many times in my career it makes me despair. The amount of wasted manpower....

"so apparently the wheels are turning slower than the engine."

Well duh. However the point is that a piston engine has a rather low max rpm compared to an electric motor, hence you need a ratio changing gearbox to keep it within a certain rev band. I really don't see what your issue is with this statement.

"google brushless motor efficiency, look at images if you don't fancy reading."

If you're going to try and be patronising it helps if you have a clue what your argument is and what the curves actually mean and how they relate to modern motor control systems using IGBTs.

"i said rarely. "

So what? Even it its only once it still needs a clutch unless you're suggesting they should push it from a standing start?

"once again, you don't need a clutch for an electric motor, whether it is mated to a gearbox or not"

Nice try. But don't try and flip the argument. You said F1 cars don't need a clutch so don't try and pretend you meant electric motors all along.

Oh FFS. Peak efficiency is for piston engines, not electric motors. Do you think theres a ratio swapping gearbox for every motor in a TGV?? Yet they still got one up to 320 mph.

"Considering f1 cars rarely stop, it's not a significant problem to forgo a clutch"

Umm, they stop for the pitstops and they have to move away at the start. Please suggest a way to do that without a clutch.

No idea why you got modded up for that comment. If you want to keep the motor rpm *up* then a gearbox is the last thing you want - just let the motor spin as fast as it can until back emf stops it or it flys apart. Gearboxes (on cars) are designed to keep the engine rpm *down*
