We redeployed our company (www.ciall.com) wiki (iCiall) a few weeks ago – based on Microsoft Sharepoint. Generally uptake has been very positive and has resulted in much better sharing of information.  One of the interesting challenges we have seen is the ongoing discussion – should I put that information directly into the wiki or should I document it using a traditional Office application e.g. notes from meetings – directly in the Wiki or documented using a minute template in MS Word (with a link from the wiki)?  And so it goes – merits of tracking business development efforts in CRM or entering on the wiki – balancing the reporting features of the CRM solution and the ease of use of the Wiki.
