I generally open a few tabs and then read through them, open a few more tabs and read through. Basically the WP site makes this impossible as the browser becomes unresponsive under the load of more than a couple of WP tabs open at once (and cannot even be left to settle down once loaded as they never finish actively eating resources both CPU time and more RAM). It makes me turn to reading articles via my RSS feed (which doesn’t have these issues but, for the longevity of the site, also doesn’t seem to have any ads so means you don’t get revenue/clicks - this would seem less than ideal for everyone).
A couple of minutes later (again, the CPU use is spikey, not constant, but never seems to drop below 4% and spikes up high):
This is latest Chrome stable x64 on Windows 10 (latest update). [Having just finished writing this, Wire Wood… is now at 770 MB and rising, holding 7-15% CPU use]
