Firstly none of my own blogs receive so many comments to a post that i would need this yet but ive seen on some busy and popular blogs that after some time the comments feature is disabled, this may be due to the articles age or maybe a limit set of the number of comments that the author/admin is willing to allow for an article. Im curious, if you have a popular blog yourself that receives many comments do you have a cutoff, like no more than 100 comments or if its more than a year old no more commenting allowed. If you do this, have you used a plugin for it?
I Normally wont do it unless its someway bad to the site... And yes i guess its part of the latest wordpress though i havent checked it out myself
I moderate the comments on nearly all my WP powered sites, so I'm usually happy to keep comments open forever. If someone makes a good comment on an ancient post, I consider it free content. I've manually closed comments on a few posts, mainly because the majority of internet users can't read or write - and they end up saying the same crap over and over again. And on some of my WP sites, I have comments disabled completely.
Thats DoDo Me, i wasn't aware of this, il have a look. Thanks Bohra I see you do what you feel suits a particular blog Kerosene or post even. Im guessing the same crap over and over is of the "great informative post" reply type.
I usually auto-close comments after 90 days of posts since after too many days, people are only interested in Spamming the blog post. You can instead put a link to your contact page at the end of closed comment posts so that genuine people who want to discuss or ask something can do so via contacting you directly.
