Tietoinen tyylivalinta, samaan henkeen kuin puheenvuoron voi aloittaa "arvoisat kuulijat" tai "moikka" riippuen yleisöstä ja kontekstista. Pikatiivistys kuvankaappauksessa muualta. Kyseinen kirja odottaa omassakin hyllyssä sopivaa lukuhetkeä!
A comment from Reddit user GaiusOctavianAlerae It’s about indicating tone and register. Texting someone “hello” vs “Hello” vs “Hello.” can have different impacts. It’s not about laziness, by the way. Since people’s phones automatically capitalize the first letters of sentences they’re often going to extra effort to decapitalize things. I highly recommend Because Internet by Gretchen McCulloch for more on the evolution of language on the Internet.

If you:
1) visit Oulu, Finland
2) enjoy occasionally eating meat
3) enjoy spicy food

I highly recommend visiting Kauppuri5 for a burger and some of their hot sauces!
It's a beast of a feast! This burger has blown up, the buns are gone and the salad is all over the plate. With the title "butcher's salad", it's the wheatless version of their perhaps most famous burger (the butcher). Ingredients in their own words: "Bacon, Beef patty, Over night braised pulled pork and roast beef, Cheddar cheese, salad bed with mustard vinaigrette, Red Onion, Kauppuri 5 BBQ Sauce". In the background, there's a small bowl of fries and an unassuming-looking but terrifyingly terrific dip sauce based on Naga Morich, a chili pepper that once held the world championship title on spiciness. Incredible and incredibly hot, even for a chili enthusiast! Served with a tasteful glass of IPA. The place looks a bit grungy, with hand-drawn art and signatures from people famous and ordinary scribbled all over the walls, and their outdoor sign has the motto "curing and getting hangovers since 2010". If that sounds like an experience you'd like to try, maybe visit Oulu?

concept: what if hair, but the other direction?
it's me! my hair has been divided to the opposite direction than usual, making it tall and poofy. this pic is with my glasses on, wide rectangles it's me again! this pic is without my glasses, although you can still see the red indents on my nose where the pads of my glasses were. hair: still poofy!

Time to re-read a wonderful classic 🧡

Behind the scenes
Two lighting stands, one with a softbox and one with an umbrella, and a tripod with the camera between them. On top of a stool is a flowerpot turned upside down, with a bunch of carnations sitting in the metal container that came with my immersion blender. Photography is all about creatively making things work 😄

I am now 100000 years old! 🎉 (or 32 in decimal)

If you want to join in on the festivities, please share some of your favorite flowers and plants 🧡

Tulips are one of my favorites, especially in simple colors - minimalist design look 🌷
A single white tulip between four green leaves. The arrangement almost looks like a hand with fingers, with the flower as the pointer

Geared up for an after work photoshoot - coworkers get new profile pictures, I get subjects, win-win!
Photography gear leaning against a wall. Godox QR-P90 softbox, Manfrotto lighting stand carrying bag, and Peak Design everyday backpack. There's also a hidden canvas bag with more stuff outside the frame!

terribly sorry for the idea as well as the execution
the same two placards as above, with red backgrounds and white engraved text, now with slight edits. the texts now read: "no human farts inside" and "no non-human farts inside". very clever, very mature 😅

early bird gets the worm - and some errands done! my head is now lighter by a bunch of hair and one tooth 🦷 hopefully the WIS -1 debuff doesn't affect my working day too much!
selfie time! it's me, a 31yo white guy with blonde hair and a new relatively short haircut, stylized to be a bit airy and poofy with wax. the background is a beautiful purple from one of the local trains.
