Three points:
1) I find Citywire pages are too resource intensive for my laptop (1.6 GHz dual core with 2 GB RAM). If I open three or four Citywire articles simultaneously my laptop cooling fan usually comes on as it works hard to cope and often one page freezes or crashes. Opening several pages on other sites is rarely a problem.
2) Citywire sends out too many e-mails with too many articles that are high on verbage but low on factual information; high on soft discussion but low on hard facts. Articles that are not about finance are easily ignored. But other articles sound like they might be informative but turn out not to be, e.g. Thursday's BOE meeting keeps interest rates on hold, Andrew Sentance wants to raise them, Adam Posen wants lax monetary policy, higher rates might stifle growth, but is it the wrong sort of inflation etc. Repeat article for each subsequent BOE rate setting meeting. Articles on your rival, Interactive Investor, tend to be fewer, more succinct and more informative. I appreciate different people have different tastes, e.g. you first Diary of a Dumb Investor was remarkably dumb but attracted about 80 replies from readers wanting to be helpful.
3) As a private investor I find your rival, Interactive Investor, provides information that is more useful and relevant to my needs.
After all that criticism I'll add that I find many of your staff are good and informed and I'll continue to read articles selectively. Perhaps one solution might be to categorise presentation of your site so that people who are into finance get tighter financial information, while the more general readership get the soft discussions, primers on how to save for retirement, personal finance articles etc.
