In addition to “Ask a Manager” which already existed in the comics aggregator, there is now also “Ask a Manager (1-day delay)” which gives you yesterday’s Ask a Manager columns. I recommend this for most people who only visit the aggregator once a day, since Alison Green, the author of Ask a Manager publishes new columns throughout the day, so if you don’t use the delayed feed you might miss some.
The flip side, however, is that by the time you read a day-old column most of the chatter in the comments has probably died down, so if you’re an active chatterer you might want to stick with fetching today’s columns. Having said that, in that case the comics aggregator might not be the best way for you to get your “Ask a Manager” fix; might I recommend an RSS feed reader? 😉
