SS Super Sunday #6: Why Do We Fall?

IGNORE THE TITLE. YOU MIGHT THINK IT'S A CLUE, BUT IT'S NOT.

Identify A - L
No sequence as such, just follow the breadcrumbs.
Scoring: +3 Points for each correct answer. +20 for all correct answers.

1. In the book A, there is a race of people whose name means a crude, brutish, obscenely coarse person.
2. Link these people to "B and C's Guide to the World Wide Web".
3. D links A, B and C to a popular online service some use even today.
4. D made a merger with E, one of the most famous tech companies around today.
5. E makes a product whose direct competition is product F.
6. G, the founder of F, released the very first issue/bug in F, which directly targeted the product made by E and marked it as one of their main challenges. This bug was closed recently in May 2013.
7. The product F is a variety of a particular piece of software H, which is at the core of several other software. Take note of "core", which is a hint at what H could be.
8. H has spawned a very famous question which goes like "Does I use H?"
9. Funnily enough, I is a "part of" or included with H and is claimed to be a better approach to mobile adhoc networking.
10. I spawned a famous meme, based on an alternate reality where J is responsible for I's miserable situation and "Proving J's guilt is my whole mission in life!"
11. L is the link between J's nemesis K and Facebook. (lateral thinking. VERY lateral)
