Getting RSS or Atom Feeds from Common Software

I choose to consume media through an rss reader where possible. If I can see the feed symbol on the page it's easy, but not all sources show it. When I can't see it, my News reader (Feed on feeds) may be able to extract it from page headers but failing that I need to find it by searching.

I can never remember what's the modifier for each option, so I've decided to create this page as an Aide-mémoire

Software	Format	URL	Notes
Blogspot	Atom	xxx.blogspot.com/feeds/posts/default	Change .co.nz (etc) to .com
Blogspot	RSS	xxx.blogspot.com/feeds/posts/default?alt=rss	Change .co.nz (etc) to .com
Tumblr	rss	xxx.tumblr.com/rss/
Wordpress.com	RSS	https://xxx.Wordpress.com/feed/
Wordpress (self hosted)	RSS	http://xxx.com/wordpress/feed/ or http://xxx.com/feed/ feed can be replaced by rss or atom	Some sites with comic authoring modules also use xxx.com/comic/feed or xxx.com/comic/feed/
