In our private lives web 2.0 technologies are omnipresent and are used on a daily basis. Even though they are everywhere, career counselors and clients are hesitant to adopt them and make them part of their professional practices. This study focuses on identifying the factors that may play a part in helping career counselors to adopt these internet technologies. Our study was conducted using a questionnaire with 286 clients and 212 professionals. A scale was specifically created and developed for this study using a facetted approach that takes into account six contextual elements (education and training, institutional policies, confidentiality, reliability, consultations with professionals, active or passive method), and five different technologies and practices (videoconferences, social networks, virtual worlds and serious games, collaborative platforms, and websites). Measuring the intention to use technology was made possible thanks to other organizational and psychological variables (openness, fear of intimacy, attitudes towards use, frequency of use, skill in use, perception of organizational resources) and their associated assessment scales. Hierarchical regression analyses were also done. For the clients, organizational, psychological, and sociodemographic variables were related to a modest proportion of the variance (approximately 12 to 13 %). Technologies involving a digital community are judged to be acceptable when clients are already using internet and when they shy away from intimate interpersonal situations. Technologies used for long-distance communication are more readily accepted when users enjoy using internet and its use is frequent. For professionals, the model explains a more significant proportion of the variance (approximately 21 to 31 %). And for this aforementioned group, three variables play a major role: user frequency, organizational resources, and attitudes towards use. The discussion offers several indications so career counselors and decision-makers can more easily incorporate these new practices and take advantage of Web 2.0’s potential for career counseling.
