Hmm I reckon most of these ITKs are the equivalent of some hooky fortune telling Madame Zozo type.
There's even no real need to follow them as all
journalists follow them and then they'll either check the validity of whatever is being claimed or, in the majority of cases, write a story based on the unfounded tweeted rumour
The only benefit of following ITKs would be if you want to get loads of gossip, or very occasionally real actual confirmation of something five minutes ahead of it being confirmed on BBC website or another more reputable source.
