Feeds not working for certain users

Feeds not working for certain users

Hi,

we are a small organisation with just 2 users, I get a feed of everything my colleague changes, ( i don't think i manually set this up). 

My colleague however does not get a feed of everything i do on zoho and he has the same user permissions as i do. 

When you go into his feeds each time it shows "write your first feed" even though we have already sent items from his feed. can you explain how i switch this functionality on for him so he can see my zoho activity in his feeds?
