The connectors are independent because the services provide completely different options. Blogger has a centralized platform for all blogs and needs the blog id for queries (there is a service to get the id from URL). Wordpress.com has also a centralized platform and needs the blog URL for queries. Wordpress.org is a distributed service and each blog has its own services so the URL is needed to establish the connection. Wordpress has a single block of actions instead of two because there is no easy way of checking if a domain is in Wordpress.com or .org (besides having a subdomain of wordpress.com) the rule is "If the URL is in format *.wordpress.com go to .com service. Else go to .org service but, if it fails, also try .com service". No editing services were implemented. Only basic read services like getting posts, comments, or pages. More details in the official API documentation: https://v2.wp-api.org (Wordpress) https://developers.google.com/blogger/ (Blogger) Possible upgrades don't include Joomla! because there isn't a single official API, neither Sapo Blogs because their API is for a different purpose.
