Found some sites I hadn't seen before and figured I'd share:
Peel.online (town of Peel, Isle of Man)
Their site logo says Peel.online. Gotta say it's definitely sexier than PeelOnline.net.
Knees.online (home appliance and furniture retailer, in business since 1879)
An
old business embracing a
new gTLD... gasp! They're even using their .online for email.
Chernobyl.online (Chernobyl - 30 years later. Online tour)
UDV.online (dentistry school in Andorra)
Seems like they may be switching
from their shorter cctld
to .online
Taste.online (specialty food store chain in Hampton Roads, Virginia, in business since 1973)
They have switched their email addresses to .online
Treebank.online (commissioned by the University of Bristol)
SaintJoe.online (high-tech elementary school in Los Angeles)
Epicurean.online (London event for wine, beer, spirits and fine food)
Also using their .online for email
Harvest.online (global equity fund)
Also using their .online for email
ApplianceOutlet.online (appliance store in Pennsylvania, in business since 1997)
They seem to have moved their site from .us to .online
So much for end users hating on new gtld's...
