I like that it is easy to use, has many features such as social media sharing which allows me reach more people with my content than ever before! It's not very intuitive for new users so be prepared or have someone who knows how things work help you out if needed!! Make sure they offer training classes at least once per year because this tool does get complicated quickly but there are some great tutorials online also available from their website too (just search).
The best thing about investorshub/advfn though compared other platforms we used previously was its ease of publishing releases across multiple channels including email listservs etc..
