Personally I don't have any issue with someone talking about something they want to talk about on their personal Twitter account.
The real question is, which of the following are worse:
a) The worthless sites which mine personal social media accounts of people working in the industry to create headlines on a slow news day drawing attention to stuff which is usually just directed to the followers of those accounts.
b) The foolish mindless fans who read said sites and then happily link to such articles because they can't help but pass along any bit of information about whatever thing they are obsessing over 24/7 at this particular time.
c) The self-righteous keyboard warriors on forums who on seeing people link to said articles feel the crusading need to tell everyone how they feel someone who is getting more attention than they are is a talentless hack or whatever.
