BTW, a note on Delicious regarding “my eye should first notice the most important link”: I prefer to also see the actual URL. Simpy does that.

As for Delicious speed – while it has Y!’s resources now, it doesn’t mean that it was written in a way that lets one just plug it into Y!’s clusters. Delicious is written in Perl, for example, and Y!’s not a Perl shop.

I cannot comment on the user base of RawSugar. There are no stats for Simpy and Rawsugar, I probably have to extend my delicious stats for Simpy and Rawsugar.. :-)

On the performance of Simpy: My performance measurements are made from europe so maybe they differ from what grabperf says.
On the performance of Delicious: It\’s a pity they cannot make their service faster. Yahoo\\\’s web search needs 0.8s per request right now (Google is two times faster) and it searches a much much bigger amount of data than Delicious does. So if they have all those resources, why can\’t they improve the performance?

On the “minimal mode”: I once did a “minimal mode” for delicious: http://www.pui.ch/del_list/index.php?user=phred&tags=firefox&title= Yes, it would be suitable for mobile devices as well. But the main advantages would be performance and less clutter, that most probably means a minimalistic UI, yes.

Please tag your relevant posts with “Simpy” as well in the future, so I can spot your insightful posts quickly. I found this one by accident, almost. Some comments.

Performance – RawSugar is the least used service, so it makes sense that it responds fast (no load). It has also been in a read-only mode for over a month now. No write operations helps, too. :)

Simpy’s performance varies by day and depends on how many maniacs are concurrently uploading their thousands of bookmarks. On a more serious note, here are real performance measurements (from servers in California)

If you look at GrabPERF’s home ( http://grabperf.org/homepage.php?page=home ) you’ll often see a picture like this:

But it can get slow, no doubt. Del.icio.us has all the resources in the world it needs. Simpy has but a couple of servers.

Don’t get me wrong, I’m not trying to make excuses, your speed observations look correct.

Regarding the results area, I can see why you rated RawSugar so poorly.

I don’t really understand what you mean by the “minimal mode”. Are you suggesting a minimalistic UI, a la a UI one would have for mobile devices?

Regarding the tagging agent, you could do this today with Simpy with minimal coding. You could either export as HTML browser file, or as XML. With XML, you could easily transform them to whatever format you wanted with a bit of XSL. Stick the transformed version wherever you want and refresh it periodically. Piece of cake.

Nice post, I’m looking forward to more of your posts about this type of stuff. Please tag them with “Simpy” if they refer to Simpy, so I can quickly spot them via Technorati. Thanks.
