If you are expecting people to read every word you write, then you may want to rethink how you write. The "F" is for how fast people scan through online materials as they seek out something that may catch their interest.
You may have the catchiest title, compelling information, or controversial topic devised for sharing with others. However, if you do not take into consideration the "F", then people will not read your materials.
There are two important aspects of contemporary writing tools: accessibility and portability. You don't have to try hard to memorize a sudden idea you get while walking in the park; all you need is a tool that lets you catch it with no delays.
Bookcrossing has a unique way of sharing books - it's users leave their old books on park benches, coffee shops etc. But the site itself also offers a community to discuss books, authors and characters.
Bookcrossing - share books via this famous community - register the book, and leave it to be picked up locally at a park, coffee shop or anywhere you purposely leave it. You can also hold a library of books read onsite for yourself.
