not all days are same for me. sometimes i end up posting as many as 30-40 comments and then there are days when i dont feel like posting anything at all.
i think one of the most important factor for me is to write about my topic of interest. i am always interested in crypto currencies and trading, so when the market has been bearish for a longer period i started writing less now that we have some activity i have a new found motivation to share more too.
thats how it is for me. i am sure others have different opinions.
