Re.
1. what is the most benefit using silo ? to make spider easy or to make link juice more powerful
Both the above!
Essentially, siloing is clustering related content
an example I often use is a "pet site"
A "normal" pet site will have the content all linked together - birds linking to cats, dogs, rodents, fish, etc.
Dogs linking to birds, fish, rodents, cats, etc.
There are 32 different ways to correctly silo a site (16 for a CMS) - but essentially the 2nd level pages (silo landing pages) are a "collective" of the 3rd level article pages in their respective silo
So, for a pet site, there will be individual silo landing pages for dogs, cats, fish, birds, rodents, etc.
e.g. a dog article can only be navigated to via the dogs silo landing page - i.e. you can't jump to a dog article from the home page, or from another silo landing page, or from a fish article page - this clusters the dog articles together - and they are directly related to the dog article page

2. in previous page, you pointed out widget in silo purpose. as per my knowledge, silo focus in main content (article). does it have value ?
That's too cryptic for me - please elaborate
Re.
3. how silo page looks like ?
Lots of options
Re.
do i need to add some paragraph or just link to article ?
You definitely need more than just links to articles - the aim is to top rank the silo landing pages - and for this you need content
Our silo themes provide a SEO text area on the silo landing page where you can "supliment" whatever else is auto-placed on the page (if article excerpts are auto placed)
Re.
and what kind of link should be, can i use naked link without anchor ? and should be like a list below right or just embed somewhere in description ?
* link1
* link2
Not sure I understand the question, but ... if you use keywords in your page titles, then you are automatically placing keywords in your links, and the page URLs
Best to look at the demo sites available via siloplugin.com home page

4. btw i am going to create news site that need get updated everyday, can i make my post non static and just leave one in homepage ? or must be static at all ? do you have any experience or words advice to warn me something regarding updated news site ?
Silo sites are best described as "static sites with dynamic navigation" - i.e. the content on the site remains the same - but the navigation to the content changes depending on which page you are on
Silo sites can have a "normal" add-on blog on a sub-domain, or in a directory - this allows the posting of "new" related content such as youtube videos, news items, etc. but you cannot silo a news site
5. can you check what techxan said in here
http://www.blackhatworld.com/blackha...ml#post7313698
it's completely true ?
Not completely!
Never use no-follow - Google changed things due to the abuse of no-follow
I'm happy with any related link pointing in to the home page from outside - I don't care if it's a level 3 article keyword, or whatever - they all build theme
Our themes do actually link the "silo tops" - but it's also correct not to link "silo tops" - just one of the permutations of silo sites architecture
Back to the "pets site" - Dogs, Birds, Fish, Rabbits, Rodents, etc. should be linked on a silo site - they're all related - i.e. pets
On a news site it would be wrong - e.g. weather, politics, health, etc. - likely to be sections found on a news site - but they're not related
I keep stressing "LSI" which is "related" - i.e. choose a "prime" keyword, then find the secondary LSI sub-keywords (silo keywords) - then find the tertiary sub-keywords of the silo keywords (article keywords) - that gives 3 levels of "related" keywords
Re.
6. lets say i had silo page published, can i edit or just create new one ?
You can edit silo pages
You should edit silo pages in order to add information on any new article added to the site - I like to have a paragraph outlining each article in the silo
You only create a new silo landing page when you have 5 or more articles ready to add to it - A silo landing page is a "gateway" to the articles that support the silo landing page
I don't think you get it! - A silo site is like a pyramid - the bottom layer (articles) are the foundation and support the silo landing pages, which are higher up the pyramid. The silo landing pages support the home page, which is the top of the pyramid. Theme (topics) flows down and across the pyramid from the top
7. can i use tags on silo site?
NO!
You can't use "related posts" either
You can't use anything that will create "extra" navigation links not already seen in the silo site navigation sidebar
