John Cook


For the last few weeks, have been thinking about adding like/dislike buttons to the blog posts and blog comments. I really only have one motivation for doing this - I want to measure the level of engagement with comments compared to blog posts. Eg - how many people read comment threads compared to the blog post and how does the readership drop off the further down the thread you get. Is there a significant drop off from blog post to comment #1? How quickly does it fall down the page and is there another significant drop off at comment #51 once the comments get to a second page?

Of course, there are lots of other benefits to such a system. It adds an extra level of interactivity. It may (can't say for sure but perhaps) encourage good behaviour knowing your comment will be rated by other ratings. If we have a scoring system - perhaps a top rating users page - that might encourage higher quality comments? I can only speculate. But all the other benefits are just gravy - specifically I want to measure readership at different points of the webpage and likes/dislikes serve as a good proxy.

So was thinking of doing something like this, with a like/dislike button at the bottom of the blog post and at the top of each comment:

(note: I borrowed buttons from commentarymagazine.com but will create my own buttons). My thinking is make the buttons available to both registered users and non-registered users. But track each like/dislike by both account (if registered) and IP address, so I can minimise the # of multiple likes from a single user.

So any comments/suggestions before I start coding? (note - I won't code this till January, go on holiday on Boxing Day until New Year's Eve).

Is there a risk that "denier-bots" will abuse the system and flood it with dislikes if non-registered users are allowed to (un)like?

Like it. Might give the lurkers some more reason to engage. Also might allows us to gauge what type of skeptic comments get more reaction


I imagine it could be done on needing to be logged in and then limited to one like per login.


Perhaps also an ad-hoc rule (or even one enforceable by programming) - no likes/dislikes from forum members. Lets see what the readership thinks

Always a risk - would be interesting to try it and see what happens. I'm inclined to make it open to non-registered users initially just to see what happens (and collect more data).

Could it make sense to set up a rating system similar to the one Peter Sinclair has on his blog? Peter uses stars to rate the blog post (1 to 5) and then thumbs-up/down for the comments posted on it. Here is an example:


I kind of like this kind of voting system as it - perhaps - gives a clearer picture of how well the post itself was rated, as opposed to how helpful a comment has been. Not sure if it would give you more or better data to "play with", however.

If it gets a 1 maybe we ask them why?
