Also I still don't understand what features does it have. Is it just clone of del.icio.us, but with screenshots and some extracted text? Or it allows to build collection of items based on data extracted from websites? I don't see any data in links I collected, but it's probably because these pages don't contain any structured data recognizable by link.fish, and rules for such data are hard-coded.

The only way to get description of what this website does is to watch video, there's no text version. I hate videos, they're very synchronous and you have to turn off music to watch them.

Sorry, have to improve the landing page if that is not clear without video. The main idea about link.fish is that it extracts the data of website and lets you work with it (sort and filter). So if you bookmark an apartment you get bedrooms, bathroom, rent, ... you can display them as list or map and that across different websites. For movies you get actors, director, ... for recipes calories, ingredients, ... and so on. Additionally, can you collaborate with other people in real-time and it creates snapshots so that even if websites get deleted you still have the page saved.

To extract the data it uses the same what search engines use (schema.org) and for pages which do not support it own rules can be defined. That rules are not hard coded they can be created by any user. If a page does not have any data there is the button "Add Domain Support". There you can then select what kind of data should be extracted (like for example a "Product") and what properties (like name, price, image, ...) and then select the data on the website. That has to be done for all not yet supported websites but then it works for all such pages on that website for all users. Not technical people can also simply press "Data Missing?" then we get a message and add support ourself.
