Done.

Channels are fetched using scraping of t.me/s/… web pages. Some channels (mostly music related) are not available on those pages.

Perhaps, some elements aren’t scraped correctly yet.

Please, test and report channels and posts that aren’t shown well.

Telegram has uber complex low level API (actually not an API but protocol — MTProto). I need to write Telegram client to read channels. Bot API doesn’t work for this, and querying channels one by one via client library quickly bumps into rate limit. So I pause this till Telegram makes normal API for getting contents of public channels.

Most Telegram channels have either RSS or VK/Facebook/Instagram equivalents to which you can subscribe.

Almost all Telegram channels just crosspost from either RSS or VK/Facebook/Instagram originals to which you can easily subscribe.
