It wasn't there before, we added it... just like we said we would.
Was it three minutes? No, it was a couple of hours of work, then another hour or so of testing.
For performance reasons, we only send down the data that a particular control needs and the template used for the thread view didn't previously need the URL of the last post, so it didn't have it. So we added it... easy enough... except I wanted to have it go direct to the right page... (by adding a Page= query string) which seems easy. You take the # of posts (since this is the last one we are talking about) and just use the page size to figure out what page it would go on, right? Well, not really... not every page on this site has the same page size, it is set by the individual template. Even if they were currently all the same (which they are not, videos have 9 comments per page, forum threads have 25) we allow each page in each site to override if it suits the purpose of that design... (maybe Mix wants 40 items per page, or no paging at all ... or 10 for forums and no paging for videos... who knows?) so you can't assume a certain page size. This possible variation means that I had to add code so that I could specify the target page size for the template (so I put pageSize="25" into the line item template for the thread list, for example) ... but then there is the case of the profile page, where the same line item template is used... in that case you could have a video, then a forum thread, then a blog post... so there had to be code that would actually go and figure out the page size of the target URL for a particular item. Once all that was done, then it was ready to be tested and shipped. None of these things were hard, but everything takes time.
Adding a link to the menu of this site, or to the sidebar of every single forum thread page... that would be a '3 minute job' (although assuming you'd want to test it, compile and run the dev site... view it in staging with release settings and then use FTP to deploy it... even a 3 minute job is probably a 30-60 minute process). Adding a dynamic URL that is affected by the entry in question and the # of other comments and has to take into account what page it is on and what page it is targeting... that isn't 3 minutes. It wouldn't have been 3 minutes in the old C9 either... it might have been quicker, because the forum thread list on that site was only ever used for that one purpose, so I could have just hard-coded the page size (in fact, I'm sure it was) ... of course, that would be a real pain if anyone ever wanted to extend, re-use or even modify that code for any other purpose.
I've always believed that the most annoying thing for any developer to hear is "that would take a couple of minutes" ... and it usually just indicates that you are dealing with someone who has never written code and doesn't know anything about it... but I know that isn't the case here. As far as I can tell, you are a professional web developer, so I don't really understand it when this comes from you. Smilie on the post or not, it seems like an odd thing to say.
