年賀状書きましたか？ December in Kyoto: Wrote New Year's Cards?

十二月の京都
12月15日から全国の郵便局で年賀状受付が始まりました。各局では元旦の朝に各戸へ届くように準備をします。家々ではお雑煮を食べお正月を祝い、ポストに年賀状が届くのを待ちます。
もうこれは「今は昔」でしょうか。
一年に一度は親戚やかつての学友、仕事仲間に日頃の無沙汰を詫び、今年の抱負を筆でしたため、干支の絵と共に送ったものです。
来年から郵便料金も上がります。
・葉書：63円→85円
・封書：84円→110円
いただいた年賀状にお返事書くだけにしようかな。LINEにしようかな。
December in Kyoto 2023
From December 15th, New Year's card reception has begun at post offices nationwide in Japan. At each office, preparations are made to ensure that the cards reach each household on the morning of New Year's Day. Families celebrate the New Year by eating ozōni (a traditional soup) and eagerly await the arrival of New Year's cards in their mailboxes.
Is this now considered as one of the past tradition?
Once a year, people used to use the occasion to apologize for their lack of communication to relatives, old classmates and colleagues, and write about their New Year's resolutions, all handwritten with a calligraphy brush on small postcards with illustlation of the zodiac animal of that year.
Starting next year, postal rates will also increase:
・Postcard: JPY63 → JPY85
・Sealed Letter: JPY84 → JPY110
Should I respond to the New Year's cards I receive only, or use LINE?
