These aren't problems, they're potential solutions to problems. Bitcoin and Blockchains are solutions to specific problems in currency and trust.

They are the structure of of decentralized systems. A comment system can be seen as (and is possibly already implemented as) an immutable ledger of transactions - adding comments, voting, edits etc.

So decentralizing those things that can be represented at their core as a ledger of transactions is very much a problem which blockchains solve.
