I'm quite surprised myself, wish my posts had received the same kind of upvotes :-) Perhaps my posts are too long and tedious ...

Regarding forks, I've written a post on the subject: Bitcoin Fork for Dummies

Segwit will not create another bitcoin type, but in November there may be a fork between the SegWit2X-supporters and the Bitcoin Core supporters. Also, if it wasn't for the SegWit2X initiative, we could have had a chain split also at the 1st of August (due to the BIP-148-crowd, wanting to force through SegWit against the will of the miners).

With the Bitcoin Cash case, the split was very clean - with so-called "replay protection" and different branding. The problem with BIP-148 and SegWit2X vs Core is that both sides want to keep the "bitcoin" brand. It may be messy.
