Jack Vinson has amplified my post on the searching part of your social filter, the other part I discussed was networking.
This post is a round up of a few ways to search your social filter:
DIY HTML search engine
Create a search engine (searchroll) at Rollyo, this will search the HTML of all the blogs, bookmark users, Twitter users, etc…
You could make 3 Rollyo search engines, one for all your favourite blogs, one for bookmark tags or users, and for for Twitter users. Each of your search engines can be accessible via a fancy bookmarklet or widget.
Google Custom Search like Rollyo lets you enter a number of sites to search and gives you a public page and a widget, make as many as you want, even load sites by OPML (it searches HTML)…see here, and more.
You can also make a custom search engine on-the-fly, by putting some code into your blog, it will pick up all the links on your blog pages and provide a search box to search those links…hmmm something Snap Shots could get into.

RSS Reader search
Google Reader allows you to search all your subscriptions, by feed or tag…so there you go, straight off you have a social filter by default…not bad at all…Steve Rubel has really taken advantage of this for data mining purposes.
Communal Search Engine
In all the examples above instead of entering the feeds of all your favourite bloggers and bookmarkers, you could add their lifestream feeds, if they have one.
One place you can make a lifestream is at Ziki by adding the feeds from your web 2.0 profiles, then you can search your lifestream, even limit to a feed. Since Ziki is also a social network you can add friends, then you can search your friends lifestreams…nice social filtering. In fact you can search the whole of Ziki, making it a general people search engine. Add a Ziki search engine to your browser.
Ziki also allows you to enter your Reading List, ie. blogs you read, I guess your lifestream is a personal filter of all the blogs you read and other content…
but you can’t search your Reading List…yes you can.
So you can search your content (lifestream) and your Ziki friends content (your network), but this is your Ziki social filter,
what about searching your Reading List as well…see below for the finale.
DIY Social filter engine
Lijit is similar to Ziki, you add your lifestream (which you can search in, even limit to a feed),
I don’t think you can add friends (it seems you can add other users to your network, only I can’t see an add friend button), instead what you can do is add your Blogroll (Reading List), your del.icio.us network, your MyBlogLog community or add any feeds you like creating a true social filter search engine (your social filter)…they have a handy widget.
It pays off blogging about this stuff.
As Jack Vinson alludes to why search the web everytime, when you can search your social filter…you have gathered sources you trust, and sources your sources trust, and so on.
Searching your network is a great quality filter for the web…perhaps the attention web.
[ADDED 12/10/07: Lijit could extend it’s offering to include some lifestream services, this way you could add a friends lifestream…saves you adding their bookmarks, blog individually.
The difference between Ziki and Lijit is Ziki is a social network experience, you can only search you and your Ziki friends. Lijit allows you to add other Lijit users to your network, but it also allows you to add feeds from people that are not registered with Lijit…this makes it a more complete social filter (not limited to a system).
As I mentioned Ziki allows you to add your Reading List, but this is not included in the search, so really they are one step away from including external feeds into your search filter, just like Lijit.
Something I forgot to mention is that you can visit someone’s Ziki or Lijit page and search the world through their eyes.
So not only do you have your social filter, but you can search the social filter of others…by adding them to your network or by visiting their profile.
See a post from Stan of Lijit that has a good visual explanation.]
