You always wanted to follow your comments to blogs, on flickr, etc.? Now the tool for this is here: coComment!
Some blogs can send you an email if some follow up is posted, but this can fill up your inbox pretty fast and many don't give this option (e.g. this one ;-). On some blogs you can get a feed, but this will clutter your feed reader and you'll have to look over many feeds after a while. So what do we need? A feed with all the comments on posts you commented to! Comment posting to older blog entries will cease with time anyway…
It's even more important for me, that coComment supports flickr now! This was always a feature I missed with flickr. There was just no easy way to follow comments on images you commented to.
The Implementation
coComment provides a bookmarklet you have to call. This bookmarklet attaches itself to a post form (if the used platform is supported) and if you press the submit button it will send the data to coComment as well (for more detail have a look at the coComment site).
So most important is to call the bookmarklet before posting!
Helper Script
I tend to forget calling a bookmarklet before posting a comment. So I started to look for a way to invoke this automatically. Greasemonkey is running anyway, so I had a look if someone had written a script to call the bookmarklet—and someone already had!
So I installed this coComment automatic invocation script and do not have to click on the bookmarklet any longer…
