Update: I hit "publish" before the article was completely finished, so I've added some images and updated some links. I can't pull the post without it leaving a trail behind it, so I may as well just own up now and say, "whoops, sorry".
GroupSwim Collaboration, in a nutshell, is a SaaS social and business collaboration tool, solution, application - whatever you want to call it. With "Collaboration", it's a hosted service by GroupSwim which could well be used as a replacement for SharePoint. Although it doesn't have all the features of SharePoint, it still works extremely well, if not better, than SharePoint in small to medium enterprises.
There are many key features of Collaboration: the main one is that it appears in forum and group form. It can be a central point of contact from a customer's perspective to get in touch with after-sales care. With forums and groups, even wiki functions for small enterprises and businesses, there are some obvious similarities with Google Groups with some exceptions. One person can be part of different groups, and with AJAX and Web 2.0 (or as it's an enterprise web application, Enterprise 2.0) style for the site, it boasts over-over tabs to get more detail on something before you look.
It can be served along side these features as a document repository. You can directly upload to a group, forum or wiki, attach to discussions you're having with work colleagues or consultants, clients and customers, or email them in using your unique GroupSwim email which is provided for you.
But... the documents aren't stored in GroupSwim. Everything's taken through the wires to Amazon S3 which significantly increases repository security and decreases bandwidth costs.
Every file has a unique page - just as SharePoint does. However what interested me was the enterprise social network feel to it. It has a version tracker and a download counter, whilst behind the scenes it's being indexed word for word, byte for byte. Because not everybody had the available plugins for viewing the documents, they use an API available from Scribd which provides the ability to access and preview those documents in full.
The wiki is something I've mentioned already. It's not like the wiki you'll see on Wikipedia, but it's included with the software and it's extremely easy to use. The design of the entire website makes it idiot-proof, which is something you'll definitely need when you've got interns working with you. With a fully Web 2.0 styled WYSIWYG editor and integrated HTML editor, anybody can use it. Even those with language difficulties can use the spell checker. It boasts automatic generation of document contents, and you can compare versions with past revisions - just in case the idiot intern decides to go on a destruction spree.
In any enterprise, regardless of whether you're a SMB or a fully fledged corporation, security is of great importance. You can secure any particular wiki, group and who can edit what and who can or can't view something. Without the overly complicated security settings you may see in other products *cough* Windows *cough*, you're given the basics and therefore the essentials: members only, specific groups of people, only you, and managers only.
Having said that, security can be altered by those who require it to a fully customisable policy for each user or groups of users. Of course again, this reduces the intern doing something stupid, and makes it even more idiot-proof.similar to the system used in Vista. With this, you can train tags to pick up on specific tags such as "SaaS", "marketing" or "whitepapers", depending on which type of industry your enterprise works with.
The search, after using it for some time, is incredibly powerful. It picks up the "standard" results in most relevant format, but can easily be switched to the most recent - in case you're looking for a document which was modified by the day, hour or minute. You can narrow searches down further with common tags which are displayed, as well as member results and group results. So it's not just a "search for a document", it's an all-round search which throws up a shed load of results, which makes it far easier to customise what you want to see from there.
If a particular user has edited a wiki page with more and more content, subscribed to group feeds and contributed to them on a particular subject; maybe if a user has published a lot of whitepapers or documents on a particular subject, they'll be given an "authority" tag next to their name in search results. The authority tag is automatically generated by Collaboration, and makes it far easier to see who the experts on a particular subject are.
Overall, it's a fantastic product which has certainly opened my eyes to other alternatives to SharePoint - something which I'm not the biggest fan of, to be quite honest.
