what are two potential shortcomings of surveys?

If you are talking about surveys similar to a public opinion survey then the size of the sample, the make up of the sample, and the wording of the question are several sources of error

That sounds like a measurement problem where the surveys when they were made did not meet at the same point and as a result there is some land between to deeded parcels of land that legally doesn't belong with either parcel of land.\n\nIn Texas that is called vacated land and belongs to the state.

Personally I avoided Surveyspaysu.com   it has a bad reputation for not paying for surveys that you do but to try to be helpful, I will share a link that I used to help me find a few good paying surveys site

You will have an issue with ip addresses if you are targeting a certain area.  For example AOL, EARTHLINK resuses IP address so you might block a new user from taking survey because IP was used by someone earlier.  I believe use a database to store username(FIRST LAST NAME) and timestamp it, then if they enter the same username within the timeframe it will deny them access with outputs like the previous example... "You have taken this survey in the last 24 hrs."   I do contract coding for small businesses, email me anytime.. lance@801promos.com

The primary shortcoming in any public opinion poll is that there is a tendency toward bias at every stage of the questioning process.  The person asking the questions has his bias; a person who wrote the question has her bias; a person who is answering the question has a bias as well.  The former two forms of bias should ideally not show up in the results of an ethically conducted poll, however they often do.\nThe next most important shortcoming is that while ideally the sample set (the specific group of people to whom the poll is given) is big enough and diverse enough to represent the general population, commonly small and/or homogeneous samples are used to save money or time or both.  Sometimes homogeneous and small samples are used by unethical poll takers to influence the outcome of their poll.\nIn short, polls will never be 100% helpful until they are designed, executed, and administered with practically no human intervention whatsoever.  But what's the fun in that?

what was said above, plus:\n\nAdvantages: can get more detailed answers, and can follow-up on responses\n\nDisadvantage:  person taking the survey can influence the results (even if inadvertantly)

in my opinion, th emajor drawbacks of focus groups are that their results have what is known as high "face-value" validity because participants' comments sound so believable. In fact, the results may appear so believable that the researcher's tendency is to rush out and put the focus group's recommendations into action without further investigation. The best plan is to wait and, before adopting specific programmatic strategies, take the time to do additional research and look for back-up of the results in the literature.\n\nAnother risk is using focus group data to generalize to a larger population. Remember that the group of participants, also known as the sample, does not necessarily reflect the entire population. For that reason, critics say that focus groups are merely an exploratory research tool. For an organization, the real question is: are the data credible enough to use in making decisions?\n\nthe major disadvantages are:\nThe moderator has less control in the group than in an individual interview. Because individual group members can influence the course of discussion, it is not always possible to know if data reflect the behavior and perceptions of individual participants or the group.\n\nBecause focus groups are held in an arranged or controlled setting, participants may behave differently than in private interviews, and this may affect what is expressed.\n\nData are difficult to analyze. Be careful not to lift comments out of context or sequence or come to premature conclusions.\n\nThe technique requires carefully trained interviewers. While an untrained moderator can achieve remarkable results it is far better to influence the odds by using skilled people.\n\nBecause each focus group is different and has its own characteristic, you must take each group on its own terms; there is no cookbook method for working with the groups.\n\nDepending on the available staff support, recruiting participants can be a difficult and time consuming process.\n\nThe discussion must be conducted in an environment that is conducive to con-versation. To attract the types of people you want, you may need to provide incentives to ensure that participants will come to the meeting.

wouldnt have to do with the amount of data and people to interpret data. Also, what about funding for the projects.\nDo you have a book on the subject. Does it require reading?

Not enough data to properly answer question.

Microsoft's Sharepoint software is really neat for creating questionaires for on-line or e-mailing.  As the others said, you need to exercise some control over your respondents. If you throw it out there for anyone, ask the wrong questions to the wrong group, etc., it will appear that you do not know grasp the concept of scientific research (which is the whole point!).
