Digg-likes reserved to members of another website as MySpace for example, are not listed.
List of general-purpose aggregators
- The pionner. See at this Adsense FAQ, to see how money a such site can make. But not all imitators will make the money!
The traffic is declining for various reasons, I guess adverts among titles, and preference to some big sites.
- News are displayed as a simple list of titles without description. Lots of comments. Subreddits allow to build your own digg-like with selected types of infos otherwise you may get a photo of the cat of each redditor around, plus lot of stupid reasonings about religion that apply physical laws to spiritual things.
You can select subreddits with a list of + followed by names of subfolders you want, ex:
And you can create a bookmark of that.
- Sacarstic aggregator with comments.

The idea of making public his favorites and share them with others have been made popular by the del.icio.us website, bought by Yahoo and became delicious.com. It has many imitators.
In fact the idea of social bookmarking was widespread and is found in social networks, and some digg-likes work similarly.

Criticism of digg-likes
Lot of digg-like were closed because of spam. Not stupid spam from webmasters who submit all post from their site, but the more subtle spam from group of bloggers who trade promotion on social sites as well as that of the fake accounts.
In June 2012, Reddit banned links on sites as prestigious as Business Week, Physorg, The Atlantic, because they have organized networks of clicks to promote their articles.
We know how using multiple accounts on Wikipedia can allow to manipulate the contents of a collaborative site. The same manipulations exist on digg-likes that bring the most visitors.
These practices are the cause of the decline of sites like Digg and probably in a near future Reddit too.
Submitting your best posts is worth so far. If they are quality they can please readers and appear on the front page and then get backlinks.
And these are not the owners of these sites who can blame them. In June 2012, Steve Huffman, co-founder of Reddit, revealed that in its early days, the site was populated by hundreds of fake accounts created by them only to give the impression that the site have contributors!
How works a digg-like
One can found on the web the entire source code of a site of this type, and also numerous articles on their operation.
- Bookmarkly is the source code of the bookmarkly.com site.
- Monocle is a link and news aggregator whose source code is available on GitHub, and which provide an interface similar to that of reddit.
- Code of connotea.org is open sourced. Was created in 2004 for scientists but available for all.
- How the Hacker News ranking algorithm works
It's a simple formula that depends on the number of votes and the time elapsed since the submission. The article, how hacker news really works, is a study of the formula which takes into account eventual penalties.
- How the Reddit ranking algorithm works
Compared to H.N. it has the added effect of negative votes. The novelty is also a more important factor. Submitted links are often downvoted by competitors to promote their own links and go to spam basket.
