Those show up with a minute of sponsored distraction inside SO MANY youtube videos (any video about math or puzzles from the last year) that I started to dislike instead of like them
An example of too much advertising having adverse effect, at least on me :p
Not comparable but airpair have a similar trick, asking to signup if you want to see their whole samples http://i.imgur.com/pVuVjrY.png and not obfuscated code samples
I run a site (http://petihacks.com) with many of these little tricks if it's the interest of anyone
That would put me off using the site, let alone registering. Especially if it's meant to be social (i.e. I'm supposed to share links to content) -- I don't want to burden other people with the same hassle.
The purpose of this bookmarklet is to provide a streamlined method of getting the selector without having to go into the source or use chrome tools.
There is also the problem of using ids. For example in Flutter I may want to auto tweet out the top post in a list of posts on a blog. If the posts have individual ids, and the CSS selector includes them, every time Flutter tries to scrape new content it will get the same post. I want the unique selector for the page element. i.e. the first post in the list.
This is built in to FireFox too. Right click element, "Inspect Element", Right click element which is now scrolled in view and highlighted in the tools, "Copy Unique Selector".
I guess having it directly on right click or in view would be useful sometimes.
