Hello Mike and thanks for the profile!

There are a few things about the current release of Simpy that are worth
pointing out:

1. Notes. None of the other services you mentioned have them
(delicious, Furl, Yahoo Web 2.0 (I think they don’t have this)). Notes
are private, taggable, full-text searchable, and of unlimited length.
There are bookmarklets for saving and searching Notes, too, and the
saving one lets you select a piece of text on a page, and save it in
your Notes (it prepopulates the “Add Note” form for you). I wasn’t even
sure if adding Notes to Simpy was a good idea, but judging from feedback
so far, people like it.

2. Topics and Topic Filters. These are perhaps poorly named, but you
can compare it to a delicious Inbox. However, unlike with delicious,
where you can have only 1 Inbox, Simpy lets you have multiple Topics.
This means you can find people who bookmark good links about swimming,
and put them in one Topic, a group of people who bookmark good stuff
about Ajax, and stick them in another Topic, and so on.
But what if people in your Swimming Topic also bookmark sites about
skiing and hiking, and you don’t care for those subjects? That’s where
Topic Filters come in. Topic Filters are essentially named queries that
you can apply to a Topic, this eliminating links that from your view
that you don’t care to see (or, thinking poisitively, filter only the
interesting links).

3. Powerful query syntax is there, but take a look at the “+ - ~” links
next to Related Tags (after a search or click on a tag). These
operators let you combine any number of tags and essentially form a
Boolean query. This becomes very powerful when you have a large
bookmark collection with a few thousand links.

4. When you look at a page for a Simpy user, you may also see “Related
Users” section (right side), if there are some similar users in Simpy.
For example: http://www.simpy.com/simpy/User.do?username=otis
(it looks like I need to exclude users with only private links - the
first related user on my list has only private links). The
“relatedness” is sometimes hard to see, but with time and growth of the
user base and the number of bookmarks and tags, the precision will increase.

5. Link History is kind of nice (I’m a sucker for graphs). For example:
http://www.simpy.com/simpy/Lin.....fox.com%2F

6. There is a REST API documented at
http://www.simpy.com/simpy/service/api/rest/

7. Easy way to try the service with demo/demo account:
http://www.simpy.com/simpy/Aut.....emberme=-1

8. Sorting links by usage frequency is nice - let’s you quickly get to
links that you visit regularly (those are most likely to be the most
used ones)

I think 1, 2, 3, and 6, maybe also 5 are worth pointing out. The other
ones are nice, but details really.

Thanks,
Otis
